Using the predefined buttons styles for the ApplicationBar in Windows 8

When you create a new Windows 8 application, the Common folder contains a file named StandardStyles.xaml. Amongst other styling resources, this file contains a trove of application bar buttons styles, including Microsoft Design-like icons. In order to use these styles, however, you need to uncomment the corresponding one. Microsoft commented these styles out, because otherwise they would be instantiated by the XAML parser when the app starts, which would cause some delays and use unnecessary memory. ......

MVVM Light V4.1.27.0 in Nuget

I just pushed a new version of MVVM Light to Nuget. The new version is 4.1.27.0. The difference towards the previous version (4.1.26.1) and this one is that I am not depending on the CommonServiceLocator Nuget package instead of providing my own.

Using async/await with WebClient in Windows Phone 8 (or: TaskCompletionSource saves the day)

When you share code between Windows Phone 8 and Windows 8, you can use async/await to code against asynchronous APIs, which is a nice step in the right direction. However there are Windows Phone APIs that do not support async/await yet. Probably the most annoying to date is the WebClient (which in Windows 8 has been replaced by a better API called HttpClient).

2012 in review

It seems it was only yesterday that I was writing about starting my 4th year at IdentityMine, and here we are now, more than a year later. The year 2012 has been particularly interesting for all of us in the tech space, and particularly for us who are observing the Microsoft brand. Now, those of you who know me also know that I am an undying optimist (something that is sometimes mistaken for fanboism), so I will make a big effort in adding a dose of realism into this billet. Nonetheless I think we ......

MVVM Light V4.1.26 change log

I just published the change log for MVVM Light V4.1.26, which is available on Nuget only at this time. The full version is available here, while the “libraries only” version is available here. I am working on an installer which will also add a few more changes to the templates and one bug fix in the code snippets. Stay tuned for that installer as soon as I figure a few things out. Important note: V4.1.26 is only available on Nuget (here and here) at the current time. An installer will be published ......

A story of Murphy–my technical issues at TechDays Switzerland #chtd

Displaying the Saved Pictures in the Windows Phone 8 emulator

One cool feature of the Windows Phone emulator is that it allows you to select pictures from your app (using the PhotoChooserTask) without having to try your app on a physical device. For example, this code (which I used in some of my recent presentations) will trigger the Photo Chooser UI to be displayed on the emulator too: Read the rest of this entry » ......

A fix for the design time error in MVVM Light V4.1

For those of you who installed V4.1 of MVVM Light and created a project for Windows Phone 8, you will have noticed an error showing up in the design surface (either in Visual Studio designer, or in Expression Blend). The error says: “Could not load type ‘System.ComponentModel.INot... from assembly ‘mscorlib.extensions’” with additional information about version numbers. Read the rest of this entry » ......

Oredev 2012: Summary and source code

This week, I had the pleasure to be invited to talk at Oredev, a really cool conference taking place in Malmo, Sweden. The whole event is awesome, including a very special dinner on Monday including sauna and swimming in a 6 degrees cold Baltic sea, and a reception with dinner at the town hall, including the mayor himself. Considering Malmo is a town of 300'000 inhabitants, it is a pretty nice occasion and the historical building itself is really worth seeing. For those interested, I placed my pictures ......

MVVM Light V4.1 with support for Windows Phone 8

Today is a very exciting day: After the official release of Windows 8 (and Microsoft Surface!) on Friday, and the official release of Windows Phone 8 on Monday, the Build conference is starting! This is the conference in which we will learn all about the developer experience for Windows 8 and Windows Phone 8. As a partner of Microsoft, I had the privilege of trying out some of the new things early, and this gave me the opportunity to port MVVM Light to Windows Phone 8 (it was already running for ......

“Using the MVVM pattern in Windows 8” in MSDN Magazine

These days I am swimming in Windows 8 code, and I must say it is a good feeling. This gives me the occasion to push MVVM Light and a few other components of mine to their limits, and to fix or improve a few things on the fly. All this goodness will be available in V4.1 which is scheduled shortly after Windows 8 launch. In spite of the busy schedule, I couldn’t resist writing an article for MSDN magazine about, you guessed it, the MVVM pattern and MVVM Light in Windows 8. It is an article that goes ......

Adventures in Windows 8: Working around the navigation animation issues in LayoutAwarePage

LayoutAwarePage is a pretty cool add-on to Windows 8 apps, which facilitates greatly the implementation of orientation-aware (portrait, landscape) as well as state-aware (snapped, filled, fullscreen) apps. It has however a few issues that are obvious when you use transformed elements on your page. Read the rest of this entry » ......

Adventures in Windows 8: Solving activation errors

Note: I tagged this article with “MVVM” because I got a few support requests for MVVM Light regarding this exact issue. In fact it is a Windows 8 issue and has nothing to do with MVVM Light per se… Sometimes when you work on a Windows 8 app, you will get a very annoying issue when starting the app. In that case, the app doesn’t not even start past the Splash screen. Putting a breakpoint in App.xaml.cs doesn’t help because the app doesn’t even reach that point! Read the rest of this entry » ......

Adventures in Windows 8: Placing items in a GridView with a ColumnSpan or RowSpan

Currently working on a Windows 8 app for an important client, I will be writing about small issues, tips and tricks, ideas and whatever occurs to me during the development and the integration of this app. When working with a GridView, it is quite common to use a VariableSizedWrapGrid as the ItemsPanel. This creates a nice flowing layout which will auto-adapt for various resolutions. Read the rest of this entry » ......

#mvvmlight V4 update for Win8 RTM

With Windows 8 RTM out of the doors (at least for some of us), it was also time to create an update to MVVM Light. I selected the V4 RTM to do this (V4.0.23).This RTM version was released a few weeks ago with no much bells and whistles because I was just too busy to write much about it. Now after some vacation, I will resume blogging on all my favorite topics including of course MVVM Light. Read the rest of this entry » ......

Fixing the certifications issues for the Windows 8 App Store and #mvvmlight

If you used the latest MVVM Light version for Windows 8, you may have noticed that a couple of issues cause your app to fail the Windows App Certification Kit. It is really quite simple: By mistake, I published the debug version of the assemblies instead of the release version. This causes the certification to fail. Read the rest of this entry » ......

Celebration! 120’000 downloads for #mvvmlight, 2 copies of Expression Studio to win

That is a symbolic milestone: Last week, MVVM Light reached the bar of 120’000 downloads on http://mvvmlight.codeplex.com, the site that has been hosting source and installers since the beginning of the project (100'000 downloads) and on Nuget, the popular package manager for .NET (20'000 downloads).

Metro design inspiration

[This is the English version of an article I wrote for the Netzwoche publication in Switzerland. This is part 2 of a 3-parts article about Metro. The original article in German can be found online on the Netzwoche website.] With Windows 8, Microsoft is going to potentially install their new design language called Metro on a massive amount of computers of all shapes, from thin low-powered slates to full scale PCs. However Metro was not born overnight and in fact a lot of research was put into it. ......

Declaring an ICommand in Windows 8 Consumer Preview

[Update 24/4/2012]

Well I'll be… after I posted this, a few people wrote to me and told me they are unable to repro the issue. I then tested again and indeed, it works. No idea why I couldn't get it to work in the first place.

The gestures of Windows 8 (Consumer preview): part 1

This blog post started as a simple one, but grew to be quite large and time consuming. I am splitting it, because I really want to publish the first findings already. Stay tuned for more! I am sure that you heard that Windows 8 was released last week in an early although quite stable stage called "consumer preview". Windows 8 is an interesting mix of touch-based and mouse/keyboard based system. Some aspects are a bit annoying (see my post about the "split personalities" in Win8 to see what I mean!) ......

Solving the ObservableCollection bug on Windows 8

If you tried to build applications for Windows 8 with XAML/C#, you may have noticed an annoying issue: If you have a list controls (for example a GridView) and you bind the ItemsSource property to a property of type ObservableCollection on your ViewModel, the GridView is not updated when the collection’s content changes. The CollectionChanged event is raised properly, but it is not honored by the binding system. Read the rest of this entry » ......

Screenshots of my #mvvm demo at #techdaysbe

Today I gave a talk in TechDays in Belgium about MVVM in Silverlight 5, Windows Phone 7 and Windows 8. This was the first time I gave that particular talk, and in addition keep in mind this is a developer preview, meaning that it is not finished, and not always stable.

Bug fix: WPF4 project template for #MVVMLight V3

Ironically, my last release of MVVM Light V3 was about fixing bugs in templates and making them better. In the process however, seems that I introduced a regression bug in the WPF4 project templates. Yep shit happens.

New MVVM Light templates with bug fixes

The current version of MVVM Light had a couple of issues in the project templates. The most annoying one was causing a problem when creating new projects: The GUIDs used to uniquely identify the project were in fact not re-generated properly every time, and we ended up with the same GUID in every new project. The symptoms are the following: If you side-load an MVVM Light application, and then side-load another one, you will see that the first one is overwritten. Note however that this is only an ......

MVVM Light Toolkit for Windows 8 (preview) #mvvmlight #win8

I was very optimistic when I first saw Metro style apps coded in C# on Windows 8, because for the most part they are not much different than the well known XAML/C# pair on Silverlight or WPF. This led me to brag a bit about probably having a port of MVVM Light ready “in a few days”. Of course I didn’t take in account that I would have a great time the week after //build in Seattle, with fantastic weather and tons of friends to have dinner and conversations with. Needless to say, the few days turned ......

Quick tip: Killing a Metro-style app in Windows 8

Metro-style apps are very similar to Windows Phone apps. They have a similar application model (for example they can be suspended, and when suspended they can be killed by the operating system if memory is needed), so they need to maintain state. Also, and that is the topic of this post, they cannot be ended by the user in a “normal” way, i.e. there is no File / Exit menu and no “X” button in the corner. Once started, the application remains in memory until the following happens: Read the rest of ......

Quick tip: Select the correct INotifyPropertyChanged in Windows 8 / WinRT

Microsoft loves MVVM and INotifyPropertyChanged so much that they included this very useful interface twice in the new WinRT framework. Unfortunately, only one of these is working correctly (and the other one is likely a bug, remnant from the past ) Read the rest of this entry » ......

Detecting design mode in Windows 8/WinRT

One of the very useful features of the MVVM Light toolkit is to help with the creation of design time data, in order to give something to see on the design surface (Expression Blend, Visual Studio designer). This is especially useful when designing list controls such as ListBox, ComboBox, etc. Without design time data, these controls will remain empty, and the designer will not see what he is working on. This can cost a lot of time and cause frustration. Read the rest of this entry » ......

Dealing with types in WinRT

Another quick tip: Most of the interaction with the System.Type class in Windows 8 is now done through the TypeInfo class. An instance of TypeInfo for a give type is retrieved using an extension method called GetTypeInfo(). Note that since this is an extension method, it will not be visible in Intellisense unless you add a reference to System.Reflection in the “using” section: Read the rest of this entry » ......

Running unit tests in Visual Studio 2011 and Windows 8 (WinRT)

My Windows 8 slate has split personalities–and what Microsoft could do to improve that

I had dinner the other night with my good friend Josh Smith, and of course we started talking about Windows 8. Something he said was pretty much spot on: He said that Windows 8 feels as if it has split personalities. There are the WinRT “Metro-style” apps and there is the “classic” Desktop, which looks and feels like Windows 7++ (optimized for touch, and actually a real delight to use with my fat greasy fingers).

What to do if the Bluetooth keyboard stops working? (#Win8 #bldwin Samsung slate)

At times it is quite tough to be on the bleeding edge.

MVVM light V3 installer for non-English systems

Automated installer for MVVM Light V3!

For a very (too) long time, the installation procedure for MVVM Light sucked. It involved downloading and unzipping files in various locations. Unfortunately, creating an automated installer is not completely trivial because of the variety of files that are getting installed: Binaries, Code Snippets, Project and Item Templates, all require different locations, and all that for VS2008, VS2010, Blend 4 and Silverlight 3, Silverlight 4, WPF3.5 SP1, WPF4, WP7.0 and now WP7.1 “Mango”.

MVVM Light Toolkit patch for WP7 Mango Beta

On Tuesday the 24th of May 2011, the new version of the Windows Phone 7 SDK codenamed “Mango” was released to the public in beta. This is a huge iteration with an extremely large number of new APIs. Most exciting, the version of the Silverlight framework now used in Windows Phone 7 is Silverlight 4. Thanks to this, I was able to recompile the MVVM Light Toolkit for Windows Phone 7 based on the Silverlight 4 version. This is interesting because the Silverlight 3 version had a few hacks I had to build ......

Is your application powered by #mvvmlight?

A couple of days ago I had the wonderful surprise to find a mention (and a link!) to MVVM Light on USAToday.com. The article talks about the new USA Today app available for Windows Phone 7. MVVM Light is mentioned as well as JSON.NET just after the high quality of the development tools is mentioned: “That same high bar for tools extends into the community as well. MVVM Light and JSON.Net were extremely useful moving past mundane tasks and instead getting to the business of building our app.” – Tim ......

MVVM Light V3 on NuGet (now with WP7 support)

There was already a version of MVVM Light on Nuget before. However the old version did not support Windows Phone 7. This is now corrected. Also the new version now adds a ViewModelLocator to your project and includes it in App.xaml. What is NuGet? NuGet is a mechanism allowing to add packages (assemblies, source code…) to an existing project. All versions of MVVM Light are supported (WPF3.5, WPF4, Silverlight 3, Silverlight 4, Windows Phone 7). In order to install NuGet and learn more about this ......

MIX08 session: Real World Design: Working with Silverlight and WPF in the Design Studio

Q: Who owns the XAML? A: Noone does, it's a tool between the designers and developers. Personal note: In my opinion, there are multiple types of XAML: Functional XAML, owned by the developer. Look&Feel XAML, owned by the designer. Also, we have a UI custodian role, a mediator between product owners and development teams. He owns the UI. Blend is used more and more as (or instead of) interaction wireframes, because oif the ease of use and how much more interactive it is. Lots of interesting questions ......

Silverlight: No more synchronous web request...

Apparently, one big thing was removed from Silverlight between Alpha and the current Beta 1: It's not possible to make synchronous web requests anymore. I must be honest: I have always been recommending against synchronous requests from a web browser to a web server. But it was nice to have the possibility to do it. I can think of a couple of scenarios where it makes sense. What I don't quite understand is why they removed it. The reason given yesterday (that it blocks the UI thread) is not really ......

MIX08: Keynote

So here we are, the breakfast was had, and now we're getting ready to listen to MIX08's keynote. I will do my best to post new information as we receive it. To make sure that you don't miss anything, check this page: http://hashtags.org/tag/mix08/ That's an interesting project: It scans through all the twitter feeds carrying the tag "#mix08" and aggregates them. Many tweeters here are using this setting, so it's a good way to keep track of what's happening in real time. I just regret that there is ......

Silverlight: Running on Nokia mobile phones

Published today in Yahoo News, the news that was announced earlier that Nokia phones will run Silverlight mobile. Great news indeed, even if the details are not known yet.

I find it funny that Yahoo News publishes this news in the "Linux/Open Source" section :)

MIX08: Random pieces of news (3)

Interesting concept for localizing Silverlight applications using a "resource" JavaScript file. Presented by Brad Abrams. Amazing set of new controls for Silverlight 2, including a datagrid. Where's the WPF-based one, Microsoft? Multiline textbox in Silverlight 2.0 (but you're not supposed to talk about it :) ASP.NET MVC framework for URL mapping. I think that ScottGu blogged about that before, something I definitely want to look into (when I'll have time, ah ah ah) Tim Sneath on WPF and Silverlight: ......

MIX08: Random pieces of news (2)

  • Next version of Expression Blend is going to be V2.5
  • Expecting another important announcement about Microsoft Expression tomorrow.
  • XNA (game development platform) may allow web programming soon?

MIX08: Random pieces of news

Expression Studio V2 is coming this April. It will include V2 of Expression Design!!! (Yes, finally) Expression Design V2 allows selecting a "slice" of your design and export it to XAML directly. Seems that the export process improved a lot. Not sure about roundtrip export-import though. V2 of Expression Studio contains Blend, Design, Web, Encoder, Media. Expression Web 2 supports PHP with Intellisense, Syntax coloring, Local preview with Cassini (development web server). Insert Flash, ActiveX, Window ......

MIX: So many amazing demos

We saw so many amzing demos this morning. My preferate... well, I loved to see .NET play chess against JavaScript. To do this, ScottG programmed a Silverlight application, and used the exact same Chess algorithm in C# and in JavaScript. This application allowed to play against the machine, and to select with engine each player was playing with, so it was possible to let the JavaScript engine play against the .NET engine. The application was displaying the number of nodes processed while running for ......

.NET support for Ruby!

That's a big news. Scott Guthrie actually demoed programming Ruby, on a Mac (so without Visual Studio), against Silverlight, with .NET!!! .NET is becoming more and more open to other technologies and platforms, and I love it. Great move.

MIX: It's starting

For those of you who read this blog from Nebula IV and are not aware of it yet, MIX is starting this week. Today is the pre-conference event, Together@MIX.This morning is packed with sessions, and this afternoon we will take part to some "fun" events. For my part, I am going to take part to a horse ride in the desert, that will be fun for sure. During the conference, I will report as much as I can on various channels: For blog reports, stay tuned to http://blog.galasoft.ch (that's exactly the same ......

MIX: Session builder missing?

Update: The session builder was made availableone day after I published this. It's available for registered user in the "sessions" area of the MIX website.

I remember that there was a Session Builder last year on MIX's website allowing you to build an agenda of session you want to see. Am I mistaken? Is this feature available now? I can't seem to find it anywhere...

Microsoft@Siemens conference

I've been taking part to a conference in Erlangen in collaboration with Microsoft. It was a very interesting event, an occasion to meet people from Microsoft Germany, and to continue the collaboration started long ago. I was asked to make a presentation about WPF, and I chose to show how we use WPF in the project I work on, and also to add a few words about the social implications of introducing WPF in a traditional, industry oriented firm like Siemens. "Social implication" is a strong word, but ......

ReMix 07 in Zurich with Scott Guthrie

Today, the ReMix 07 event is taking place in the World Trade Center in Zurich, Switzerland. Lots of great speaker, includign Scott Guthrie, Wayne Smith, Beau Ambur and more. Wayne Smith just showed his video encoding and XAML editing demo, pretty much the same demo as in Vegas, but very well received here anyway! You got to love his accent :) but more important, the content is great. One new thing presented today compared to the Las Vegas edition is a new plug-in for LiveWriter which allows embedding ......

ReMix Zurich tomorrow

ReMix 07 Zurich I will be attending ReMix in Zurich tomorrow. This event will be specially interesting this year due to the presence of Scott Guthrie for the keynote and 2 presentations. I'll hear even more of Scott in the evening, at the DotMugs (.NET Managed User Group of Switzerland) where he will be speaking about ASP.NET and Orcas. I am very happy to hear Scott again, this will be the thrid time (after MIX06 and MIX07), and I sure hope I will have many more occasions ......

Silverlight: Passing null values or empty strings (revisited)

(wrote this in the plane from JFK to Las Vegas) In a previous post, I mentioned that it's not possible to pass empty strings from JavaScript to a Silverlight application. It seems that it was not correct, or at least not complete: It is in fact possible to pass null values or empty strings, but not the content of an empty HTML textfield (input type="text"). Let's see: <body> <div id="SilverlightControlHost" class="silverlightHost" > <script type="text/javascript"> createSilverlight(); ......

MIX: Building the schedule

I am in Princeton NJ for the weekend, after spending a few days with our graphics designers, working on our WPF application. It was very nice again, and I love the new design we have. I miss my family, but determined to make the best of this trip and to take life positively as usual. I plan to drive down to Philadelphia tomorrow for a short visit (I have been in Philly once before, in 2001). I finally managed to build my schedule for MIX. I was very strict this year and selected only maximum two ......

MIX day 3 (cont)

Gee, I almost forgot one session I attended: Booyah! Designing and Developing Line-of-Business Applications That SIZZLE Once again a nice demo, concentrating on the specific problems and challenges you encounter when you develop 3D applications. Nathan designed beautiful glass tubes which are filled with data. I loved his mention that in WPF, he is actually working with materials and textures. When he says that, I get the impression that his working is actually sculpting 3D objects. I think that ......

MIX day 3

Today was MIX's last day, and it's almost painful to have to leave. I can't believe how fast it went, how packed with information it was, and how many great people I had the chance to meet. To all of you, I want to say thanks for the great time I spent here. The organization was, as usual, spotless. Now I have so much information to process and sort, this will keep me busy for a long time... Oh how I hope to make it to MIX08 ;-) Extending the Browser Programming Model with Silverlight If I had to ......

#twitter for Windows Phone 7 protips (#wp7)

I started tweeting a list of “protips” (or whatever you want to call that) related to the Twitter for Windows Phone 7 application. Since I worked as integrator on this app, my tasks involved integrating design assets in all screens, and so I had an insider view on all the screens (and that is really a LOT of screens :) Seeing some comments about the app made me understand that most users out there don’t realize how rich the application is, and how many features are available. So without further ado, ......

Silverlight User Group of Switzerland (SLUGS)

Last Thursday, the Silverlight Firestarter event took place in Redmond, and was streamed live to a large audience worldwide (around 20’000 people). Approximately 30 if them were in Wallisellen near Zurich, in Microsoft Switzerland’s offices. This was not only a great occasion to learn more about the future of Silverlight and to see great demos, but also it was the very first meeting of the Silverlight User Group of Switzerland (SLUGS).

Watch the #Silverlight Firestarter event with us!

On December 2nd, Microsoft is having an exciting event in Redmond: The Silverlight Firestarter.

Back from TechEd Europe 2010 (Berlin) #tee10

I spent this week in Berlin in company of about 5000+ other geeks at Microsoft’s TechEd Europe.

This year however I was invited to give two talks and participate in a panel of experts. Read the rest of this entry » ......

Microsoft Shape

Today I have been invited by Microsoft Switzerland to present three of our awesome Windows Phone 7 applications on stage at their yearly Shape conference. It was a great moment, and I felt super proud to show the IMDb app, the Twitter app and the SBB Mobile app. The response was excellent, I didn’t have one single demo effect, was able to stream a movie preview live from the IMDb app, to show most features of the Twitter app, to load a timetable and purchase a ticket from the SBB app, and all this ......

Adding a ViewModelLocator and Merged Dictionaries to App.xaml

I guess this is one of these places where using Blend is an advantage… since I do these operations mostly with the help of the tool, the XAML is generated and I don’t need to think about it too much.

JavaScript vs Silverlight: An answer

How to use the MultiTouch Behavior for Windows Phone 7

Yesterday, I published the source code of the MultiTouch Behavior for Windows Phone 7 on Codeplex (http://multitouch.codeplex... Meanwhile, Davide Zordan (the founder of this project) started to modify the Silverlight 4 version of the behavior to make it API compatible. Eventually, the goal is to share all the API signature, and as much code as possible. We would like to extend this to the WPF version as well, in order to have a consistent landscape of multitouch on all 3 platforms. Read the rest ......

Two small issues with Windows Phone 7 ApplicationBar buttons (and workaround)

When you work with the ApplicationBar in Windows Phone 7, you notice very fast that it is not quite a component like the others. For example, the ApplicationBarIconButton element is not a dependency object, which causes issues because it is not possible to add attached properties to it.Read the rest of this entry » ......

Handling DataGrid.SelectedItems in an MVVM-friendly manner

An interesting question from one of the MVVM Light users today: Is there an MVVM-friendly way to get a DataGrid’s SelectedItems into the ViewModel? The issue there is as old as the DataGrid (that’s not very old but still): SelectedItem (singular) is a DependencyProperty and can be databound to a property in the ViewModel. SelectedItems (plural) is not a DependencyProperty. Thankfully the answer is very simple: Use EventToCommand to call a Command in the ViewModel, and pass the SelectedItems collection ......

Be careful when installing the Blend Windows Phone 7 Add-In

There was a small issue today with the release of the Windows Phone Developer Tools CTP (April 2010 Refresh) refresh. The issue is that the Expression Blend Add-in Preview for Windows Phone (April Refresh) is not compatible with Blend 4.0.20408.0, which was the public RC (release candidate).

Crowdsourcing MVVM Light Toolkit support

Considering the number of emails that are sent to me asking for support for MVVM Light toolkit, I find myself unable to answer all of them in sufficient time to make me feel good.

Using commands with ApplicationBarMenuItem and ApplicationBarButton in Windows Phone 7

MVVM Light Toolkit V3 SP1 for Windows Phone 7

He he I start to sound like Microsoft… Anyway… I just released a service pack (SP1) for MVVM Light Toolkit V3. Why? Well mostly because I worked a bit more with the Windows Phone 7 tools that were released at MIX0, and I noticed a few things that could be better in the Windows Phone 7 template. Also, I only found out at MIX that you can actually install custom project templates for Visual Studio Express. For some reason I thought it was not possible. Read the rest of this entry » ......

Sample code and slides for my TechDays10 (Belgium) talks

The source code for my MVVM talk titled “Understanding the MVVM Pattern” given at TechDays 2010 in Antwerpen, Belgium, is available online.

Multithreading in Windows Phone 7 emulator: A bug

Multithreading is supported in Windows Phone 7 Silverlight applications, however the emulator has a bug (which I discovered and was confirmed to me by the dev lead of the emulator team): If you attempt to start a background thread in the MainPage constructor, the thread never starts. The reason is a problem with the emulator UI thread which doesn’t leave any time to the background thread to start. Thankfully there is a workaround (see code below). Also, the bug should be corrected in a future release, ......

MVVM Light V3 released at #MIX10

During my session “Understanding the MVVM pattern” at MIX10 in Vegas, I showed some components of the MVVM Light toolkit V3, which gave me the occasion to announce the release of version 3.

My program at #MIX10

Getting ready to fly to Vegas and MIX10 is really an exciting time! It is also a very busy time, because we are working on a few projects that will be shown on stage, I have my presentation to prepare, and of course as always the book… though these days it has been a bit on the back burner to be honest ;) I arrive in Vegas on Sunday evening around 10PM, so I won’t be able to make it to the traditional IdentityMine dinner this year. I am sure it will be fun nonetheless! Read the rest of this entry ......

Schedule for my session at MIX10

Microsoft has published the schedule for the MIX10 sessions. I have a sweet spot, and I dearly hope that it stays this way (Last year I had a great spot, but it was changed last minute and then I had a much better one, “competing” against Vertigo and their Playboy app… yeah try to explain to a bunch of geeks that MVVM is better than Playboy… good luck with that ;) Anyway, this year my sweet spot is on the very first day of the conference (there are workshops on Sunday, but this qualifies as pre-conference), ......

Silverlight MVP of the year

Here is a quick news from the MVP summit in Redmond. Things here are amazing, with a lot of good news (that will be made public at MIX, so in the mean time I cannot say anything more about it, except that it is awesome).

The MVVM landscape at MIX10

Update: Shawn Wildermuth has changed his session and will be talking about Silverlight Security instead. The MIX conference this year had an open call for sessions, and 12 sessions were voted by the public out of 169. Surprisingly (or maybe not that surprisingly in fact), 3 sessions out of the 12 have the MVVM pattern in their title. This shows a lot of interest for this pattern which is helping the developer to create decoupled, testable, blendable applications in Silverlight and in WPF. Read the ......

Avoiding issues when typing text in Bindings

Talking in Las Vegas: MIX2010 and MVVM

This morning, very early (or very late depending how you see it), I learned that one of the sessions I submitted to the MIX 2010 open call for speakers had been picked by the public. Out of 169 sessions, only 12 were picked, so you imagine my feelings right now. Honestly, I am sure that this will be a good session, but it could have gone either way, and I had prepared myself mentally for the alternative possibility too. Read the rest of this entry » ......

MIX 2010: Voting for sessions has begun (I got two)

This year Microsoft decided to have an open call for sessions for the MIX 2010 in Las Vegas. This conference, in case you don’t know it yet, is a great 3 days about modern client technologies, such as ASP.NET, Windows Presentation Foundation and of course Silverlight. This year, MIX is taking place from the 15th to the 17th of March 2010 in the Mandalay Bay hotel in Vegas. Today, the voting began! I didn’t count them, but there seems to be more than 100 sessions lined up, and the competition is fierce: ......

Silverlight 4: Drag&drop with EventToCommand

One of the MVVM Light Toolkit’s user requested that I add the possibility to pass the EventArgs of an event to the ICommand that it is bound to through the EventToCommand trigger. At first I was a bit reluctant because it seems like a transgression of the rule that says you should avoid to have too much knowledge about the UI layer in the ViewModel. For example, if you have a RelayCommand in the ViewModel that expects a MouseEventArgs, it kinds of binds you to a certain kind of UI element, which ......

MVVM Light V3/alpha3 for Blend 3 and Blend Preview 4

The project and item templates allowing you to create pre-wired MVVM Light applications are now also available for Expression Blend 3 and Expression Blend Preview for .NET 4 and Silverlight 4.

Bug correction in Messenger and new feature in EventToCommand (MVVM Light Toolkit V3 alpha)

Update (11/14/2009): The sample application is available as a zip file, and I also published the Silverlight version to be executed directly in your browser. The advantage of pushing very early software to the advanced users is that bugs are detected before too many people suffer from them, and features requests can be placed and implemented without pain. This is exactly what happened with the MVVM Light Toolkit V3 alpha 2. Read the rest of this entry » ......

MVVM Light Toolkit Logo by P. Schutz

I met Philippe Schutz at the TechDays in Geneva early this year, and have been following him on Facebook since then. He does amazing work with logos and icons, and it is only natural that I have thought of him when I decided to get a new logo and icons for the MVVM Light Toolkit. A brand identity is quite important to me even in private projects. This is why I created the site GalaSoft (www.galasoft.ch) years ago, and started using this “brand” consistently as well as the cat logo (more about that ......

Using RelayCommands in Silverlight 3 and WPF

Like most of us have found out the hard way, Silverlight 3 and Windows Presentation Foundation 3.5 are two quite similar beasts, but not totally the same. Silverlight is often presented as a subset of WPF (in fact, some features are available in Silverlight but not yet in WPF; generally speaking, though, it is true that Silverlight has less features than its big sister WPF) (yeah WPF is a girl, don’t tell me you didn’t know ;)) Read the rest of this entry » ......

Detecting design time mode in WPF and Silverlight

We already talked often about providing design time data to your designers in Windows Presentation Foundation and in Silverlight, thus enabling them to work visually in design editors such as Expression Blend or the Visual Studio designer (codenamed Cider).

Polymorphic Podcast: MVVM, Blend, Integrator in WPF and Silverlight

Some time ago, Craig Shoemaker asked me if I wanted to talk about design time data in MVVM on his Polymorphic podcast, and of course I said yes. Following in the steps on my buddies Josh Smith and Tim Heuer was a bit scary, but hey, this is what we do, right, following the steps of giants and trying not to look too silly while we do it :) Read the rest of this entry » ......

Expression Blend Samples InvokeDataCommand bug

My good friend and super hero programmer Pete Blois posted an impressive collection of samples using and extending Expression Blend behaviors and triggers on Codeplex some time ago. There are a few real treasures in there, and some of them that I would like to integrate in my MVVM Light toolkit, thus avoiding to reinvent the wheel. I am still checking the license (the Samples use the MS-PL license) but I think it should work just fine. Read the rest of this entry » ......

Working on a MVVM “light” toolkit

As some of you now, I have been spending most of my free time (which is not much these days once I am done with the amazing projects I am working on at IdentityMine, and the time spent with the family) working on a very simple, very light MVVM toolkit.

This toolkit will encompass

HP Touchsmart TX2 keyboard failure (and the cure)

Installing Windows 7 from a USB drive

Yesterday, Windows 7 RC (release candidate) was published on MSDN, so the subscribers are currently downloading it. I have been using Windows 7 since October 2008, when it was pre-released during the PDC conference. Then I moved to the beta when it was released, and have been using it as my main system since then. I almost never had to go back to Vista (which I kept installed on another partition of my main laptop, just in case). Read the rest of this entry » ......

Switching expertise: From Client App Dev to Silverlight

Posting the source code for #techdays (Switzerland) talks

Update: I updated the installation instructions to make it clearer that you need the WPF toolkit and SQL Server express before you can run the application. TechDays Switzerland is always a very nice venue, and this year in Geneva and in Bern were no exceptions. For me it was a special occasion, because I gave the same talk in French in Geneva, and in German in Bern, and I had never done this before. I think it went well. Altogether approximately 450 people saw this talk. I think I will possibly reuse ......

Using a Behavior to magnify your WPF applications

At MIX 2009, the Expression Blend team cam up with a new concept called Behaviors. In fact, the only thing new is the way that the Behaviors are packed. WPF developers have been doing what we called "Attached Behaviors" for quite some time already: see this thread (dated July 2008) to read a discussion around this topic at the WPF Disciples group.

Solving cross domain access problems (via Jon Galloway)

A Tribute to the WPF Disciples

A very long time ago, I was contacted by Marlon Grech who asked me to join a new Google group he had just created called the WPF Disciples. I was quite new in WPF back then and didn't know many members of the community yet, and I must admit that it slipped my mind and I didn't register (when you blog, and your blog gets a certain visibility, you get all kind of requests. I do my best to satisfy most of them, but sometimes I am just too busy and I cannot follow up). Read the rest of this entry » ......

TechDays Belgium is over

I just held two talks in Antwerp, Belgium, for TechDays and it was really nice. First the Belgian team did a fantastic work welcoming the speakers, and as far as I could say, the attendees were also taken care of in an exemplary way. We had just a small incident (there was a power breakdown about 15 minutes before my show and the whole center went black), but noone panicked and it was taken care of with a lot of care.

Back from MVP summit and heading to Tech Days Belgium

I am just back from the MVP summit in Seattle / Redmond and I had a great time there. It was fantastic catching up with old friends and making new ones. Seeing what is coming up in future releases of Silverlight and WPF (to name just those two) was electrifying. Of course I cannot talk about it because otherwise Justin Angel and the NDA police will track me down and kick my ass. If you never met Justin before, trust me, you don't want that to happen. :) Read the rest of this entry » ......

Talking at MIX09: Las Vegas and the continuum

One of my dreams is going to come true: Since the very first time I attended MIX in 2006, I have wanted to talk there. MIX has a very special meaning for me. It is in the Venetian conference rooms that I heard about Windows Presentation Foundation and what would later become Silverlight. It is there that me and my two colleagues Andreas and James decided that we wanted WPF for the project we had just started at Siemens. A decision that was definitely the right one, from a technical point of view ......

MIX10K contest: The choice is made

As I blogged before, I was one of five judges chosen to decide which of the 105 (!) entries in the MIX10K contest were the best... it was a hard, terrible choice, but now the results are public! As a reminder: The contest is organized by Microsoft at the occasion of the MIX conference that will take place in March in Las Vegas. The goal was to create a Silverlight or WPF application with only 10 kilobytes of code (about 10'000 characters of text, including spaces, carriage return, etc...) Read the ......

The talk will be the same as in the TechDays in Bern, but this time it will be given in French.

Weird color effect with Windows 7 and LiveMesh

I’ve been testing Windows 7 in real life conditions for the past few weeks, and am happy to report that I didn’t need to fall back to Vista at all so far. There are a couple of very small details that bug me a little, but I am not even sure if they’re related to Win7, so I just live with them for the moment.

I was kind of sad that Kevin Dente and Scott Koon didn't manage to join us, but the conference was so packed with events that we found time only on the very last day (Thursday) and the two had to go back home already.

#PDC08 pre conference: WPF Code and Concepts by Charles Petzold

According to Charles Petzold, WPF is the main platform for Windows programming nowadays. The only reason why one might still want to program WinForms is if you want the app to run on a maximum of machines. Petzold says he was resistant to XAML when he came to it first. But now, over the years, he is very comfortable with it and uses it a lot. You should give a chance to XAML. Interestingly, he took in his talk the exact opposite approach from his book: Starting with XAML only, and then only moving ......

Redesigning my website with the help of Expression Blend

I decided to completely redesign my website www.galasoft.ch (yes, it's about time, I know). For this process, I decided to inspire myself (loosely) from my good friend Robby Ingebretsen's site, which is both simple and beautiful. In order to get a better idea of what I want to reach, I decided to work like most web designers and to create a mockup first. Instead of creating a static picture, however, I used Expression Blend, a tool I am fairly proficient in, to create a WPF application demonstrating ......

One Tweet by Oliver Sturm (http://twitter.com/olivers) the other day got me to thinking.

Currently, there are 3 possible ways that I know of to render XAML in a web browser Loading the XAML file directly in an IFRAME will trigger Windows Presentation Foundation on the client (if available). The IFRAME can be positioned in the page so the it "blends" with the HTML page. That's only for ......

Microsoft to add jQuery in Visual Studio: Why I think it's great

The news took the community by surprise and the reactions are overwhelmingly positive: Microsoft is going to ship jQuery with the ASP.NET MVC framework (very soon) and with Visual Studio (in a near future). For more details, ScottGu and Scott Hanselman are talking about that in a very complete way. I think it's great news on many levels. First, because I hear that jQuery is a great framework. I must admit I never used it, because I didn't do much web development lately (but I will get back to it ......

Silverlight 2 Release Candidate 0 *for developers only*

So many people blogged about it already (time difference, and fun dinner last night, so I am late :) that I prefer to just point the reader to the best possible source of information: Scott Guthrie's blog. It cannot be stressed enough that this release is for developers only. It might very well be the last release before the final is made available, so it's a chance for people with Silverlight content to update their code. The public runtime will not be updated to RC0 automatically. So do *not* publish ......

Silverlight 2 Unleashed: Table of Content

I am currently attending a workshop for Siemens in Chicago's suburb, and also staying for the weekend.

Which is why I am now writing a book about Silverlight 2 Unleashed (available on pre-order at Amazon and to be published really soon :) I finished reviewing the very last chapters ......

Sams Silverlight 2 Unleashed (was: Teach Yourself Silverlight in 24 Hours)

My editor at Sams (hey Neil :)) and I decided to convert the book I am almost done writing into an Unleashed. There are multiple reasons for that, the most important being that the book addresses multiple audiences, and has a broad range of coverage, which is typical of the Unleashed series. The content goes enough in depth (according to Neil) to be placed in the Unleashed series. While the Unleashed series usually targets more advanced users than the Teach Yourself one, this book has lots of content ......

I just posted today's talk at the RIA conference in the World Trade Center, Zurich. Unfortunately it was not recorded, but the slides and the demos' source code is available on my site. The talk went really good, even though the crowd was rather tough :) Trying to "sell" Windows Presentation Foundation, a desktop Windows-only technology, to an audience of web developers, many of them using Java and open source technologies (and even one Adobe employee) sparkled some very interesting discussions. ......

TweetMyPage V0.2 - Now with "from TweetMyPage" indicator

As soon as I had my info page online, I asked Twitter to accept TweetMyPage as a Twitter application, and to mark the messages posted with TweetMyPage with "from TweetMyPage". Note for developers: There is a form to fill on the Twitter API page. It's really fast, and one day later I got the answer that it was accepted. From now on, messages posted from TweetMyPage are marked as such: I got a couple of testers so far, and already got a few requests for additional features. I am now evaluating how ......

WPF talk this Thursday: "Ultra Rich Interactive Applications"

I have been in very much stress lately and hardly had time to post, but I don't forget you, dear readers... Anyway, this Thursday, I will be talking in a RIA conference organized by the Internet Briefing group here in Zurich, in the World Trade Center. My talk is titled "Ultra Rich Interactive Applications with WPF" and subtitled "When Silverlight is not enough...". I think it's going to be an interesting talk (but obviously I am partial) about the major differences between WPF and Silverlight, and ......

My resume is now online

I finally did something I wanted to do for a loooooong time: I cleaned up and put my resume online on my website. Note for Beat (my boss), if you read this, don't panic, I am not leaving just right now :) Anyway. For those of you who like to know my (professional) self better, feel free to take a look. If you want a username and password to check my certificates and awards, contact me. And if you have any comment, give me feedback ......

WPF: ListView/GridView minimum and maximum width for a column

A WPF ListView is a possible replacement for a datagrid, when it doesn't have to support advanced features like grouping or filtering of rows. If you use a ListView in your WPF application, and set the "View" property of this ListView to be a GridView. A ListView/GridView even supports features like reordering and resizing columns. Unfortunately, it is not possible to define a minimum or maximum width for the columns. Fortunately, it is not really to do this in the code behind. Let's see how. First ......

Silverlight: User Controls with events

This article is for Silverlight 2 beta 1 Update: Corrado Cavalli translated the example in VB.NET. Thanks Corrado!! Apparently, one reader had issues declaring events for the User Control example that I posted earlier this week. He is programming in VB and unfortunately I don't have a lot of experience with VB.NET, so I first created a working example with C#, and my good friend and fellow MVP Corrado Cavalli translated the example in VB.NET (see below). The big difference between WPF and Silverlight ......

Silverlight: Running standalone full trust applications

Introduction I guess that it's time to write about it, after making a few people curious at the MVP summit in Seattle. This article is to be taken as a proof of concept, and (I hope) as a way to "motivate" Microsoft to integrate this ability into Silverlight. As soon as I started playing with Silverlight, I saw the great potential that this technology has. As a RIA technology, it provides extended functionality over the web. As a WPF subset, it allows me to leverage the knowledge I already acquired ......

I am now a Microsoft Certified Professional

What a crazy week that is. I am currently in Seattle for the Microsoft Most Valuable Professional summit, which ended yesterday. I took an additional day in Seattle to meet a few friends and Siemens colleagues, and this morning got an email notifying me that I passed the MCTS exam about WPF that I took back then in December. Because the exam was in beta stage when I took it, Microsoft needed a veeeeeeeery long time to evaluate the replies and check if I met the requirement. Apparently, they also ......

Silverlight: Packing user controls in separate assemblies

This article is for Silverlight 2 beta 1 There is a common misconception that User Controls in Silverlight must be placed in the assembly from which they are referenced. However, this is not true, you can have user controls in an assembly and use them from another assembly. This is not a direct process, however, so let's see how to proceed: Preparing the control Create a new Silverlight 2 application in Visual Studio. In this example, we'll name this application "UserControlsPacking". For this first ......

#mvp08: Day 1 and 2 are over, more to come

Today was day 2 of the Global MVP Summit. We spent it in Redmond, on the Microsoft Campus. For my part I spent the whole day in the RIA (pronounced "reee-ya") track, focussed on Silverlight (mostly) and WPF (a little). I won't say much about it for two reasons: Either the code we saw was very similar to the one shown in Vegas one month ago, or I don't have the right to talk about it because of NDA Generally speaking, it's safe to say that really great things are going to be built on top of Silverlight. ......

#mvp08: Arrival at Global MVP Summit

Day 0 Oh man what a trip. First I left home at 6:30AM, which on a Sunday (and my birthday) is pretty more a crime against humanity. Additionally, I was woken up a few times during the night: Twice by my elder daughter who came to check if my bags were still there, because she was afraid to miss me to wish me happy birthday in the morning (she opened her door at 2:30AM and 4:30AM, both times waking me up of course :) Then after taking the train to the airport, I learned that my flight to Frankfurt ......

#mvp08: On my way to Seattle for the MVP Summit

It's my second year as Microsoft MVP but I didn't attend the global MVP summit last year, so I am really excited to attend this year. I am currently on my way to Seattle (via Frankfurt), and will spend next week there getting loads and loads of information about the newest trends and technologies from Microsoft. Like any conference, the summit is also (and before all) a way to network, meet new friends that I know from their blogs or Twitter or any other e-medium, and meet again with friends from ......

De WPF Integratio (About WPF Integration)

Introduction I've been posting a lot about Silverlight lately, but hey, here is a WPF post, and about WPF integration, no less. Note: To fully understand this article, you should have a basic understanding of WPF, styles and templates, triggers, etc... In my current project at work, I act as WPF Integrator. I am that dude who sits between the designers and the developers, and tries to avoid that they fight too much. Or something. Sometimes it works, sometimes it doesn't, you know how it is with kids. ......

Silverlight unit testing and JavaScript

I am currently writing a Silverlight class library which I want to use in a project, and decided to try Test Driven Development for this class. This is a really nice way to work, and the Silverlight development team made this very easy by providing a unit test framework easy to integrate into Visual Studio 2008. (Note: You cannot simply use the built-in unit test framework, because a non-Silverlight application cannot reference a Silverlight class library). To find information about where to download ......

Silverlight Bug: Transforms and OpacityMask

Introduction In WPF, one of the best know effects is the "reflection" effect, where a scene reflects itself dynamically. It's a very cool feature, because it's really easy to realize, and it allows to reflect images, but also videos or other User Interface scenes. The key to this is to use a VisualBrush. Silverlight is not exactly as powerful as WPF, and doesn't have VisualBrush, but it has ImageBrush and VideoBrush, both of them allowing cool media reflection effects (these brushes can also be used ......

Community Credit 6th prize

I am humbled and also wondering. Humbled because I learned that I got the 6th prize in March Community Credit. Wondering, because I was at MIX in March, and blogged a lot (by my standards) and I am only 6th :) I will never get first prize I guess! Thanks David Silverlight!! Can't wait to receive my Digital Dog ......

Silverlight 2 beta 1: ScrollViewer with auto-layout crashes both IE and FF

Update 2: The Silverlight team at Microsoft was able to reproduce the bug, and it has been entered in the bug database. Thanks all for your precious help!! Update: Apparently this bug is not consistently reproducible. If you get the bug, please enter a comment with your system information. I was able to reproduce on a number of machines and OS, but on some other PCs it works just fine. Here is an interesting one: <UserControl x:Class="GalaSoft.SL.Scroll... xmlns="http://schemas.micro... ......

Silverlight: The Power of Skinning by Corrina Barber

If anyone still needed to see the Power of Skinning for Silverlight controls, well, Corrina just did it (again). In addition to the 3 existing skins "Bubbly", "Red" and "Flat", she just published a 4th one "Rough" (click on the links for a live demo, requires Silverlight 2 beta 1). More information about the skins, including a download link for the source code, can be found on Corrina's blog (Bubbly, Red, Flat; Rough) Rough skin Bubbly skin Red skin Flat skin ......

Silverlight: Downloading Zipped files with the WebClient

In the "old" alpha edition of Silverlight, you could use the Downloader class to download a zip file containing one or many packed media elements (images, videos). The Downloader provided a progress report (to update a progress bar, for example). After the download was completed, you could use the Image.SetSource or MediaElement.SetSource method to directly unpack one file from the downloaded zip file. In Silverlight 2 beta, the interfaces changed, but you can still do the same operations. Let's ......

TechDays 08: Talked about WPF and now back home

The Swiss edition of the TechDays 2008 is over. It was a great success,many people came, and as far as I can say, people had a good time. I didn't attend any sessions though, because I hung out in the main area instead and met a number of people (some of them I knew from MIX or other occasions), and talked talked talked. Yesterday evening, there was a party, I didn't stay too late though because I wanted to be well rested for my talk this morning. My talk titled "Siemens goes WPF, Lessons learned" ......

Silverlight: Don't forget to add the XAP extension!

Silverlight 2 now packs all the files needed to run the application in a XAP file (which is essentially a ZIP file). Think of the XAP file a little as the JAR files of Java applets. Because these files must be served by the web server in the correct way, it is necessary to pay attention to this extension (we had exactly the same problem when XBAPs were introduced, or for serving "pure XAML files". Brad Abrams has a post explaining the problem, and showing how to configure your IIS6 web server. If ......

TechDays 08: My talk next Thursday in Basel, Switzerland

Next week, on Wednesday the 19th and Thursday the 20th of March, the TechDays Switzerland will take place in the St. Jakobshalle in Basel. Apprently, it's sold out and they expect around 2300 people in 5 parallel tracks. Now that's kind of making me nervous, because I will be presenting a session on Thursday the 20th at 9AM!. It's not the first time I'll be talking at a conference, but it's certainly the first time that so many people will attend, so... kind of nervous here : The talk is called "Siemens ......

#MIX08: Wrap-up post

MIX08 is over, and I am home with what one could call the "post-MIX" mood. It's a mix (pun intended, haha) of various feelings Obviously I am extatic to be with my family again, even more so because I was away for almost two weeks, which I usually try to avoid. It's just so good to be with them again. I wish I could take them with me every time I am abroad. Excitement about all the new things we saw. Thinking all the time of what I'll be able to improve in my various projects using these new techniques ......

#Mix08 Session: What's New in Windows Presentation Foundation 3.5

#Mix08 Session: Nerd + Art: Ten Code Snippets to Empower Your Inner Artist

Robbie Ingebretsen: "This is a creative experiment" "We didn't always look into best practices" Talks about the Integrator role. Nathan Dunlap: "Designers should probably use Visual Studio more" "It's a great tool to dive into the code,check the SDK..." Snippets are distributed as a Snippet installer VSI file. Silverlight code snippets WPF code snippets By the way, check Dr WPF's snippets too! To access the Nerd snippets in the code, simply type "nerd". Displays the list of all snippets. Custom Control ......

#Mix08 session: Overview of Expression Encoder 2

Expression Encoder 2 is now a standalone product, not part of Expression Media like before. Download it from the Microsoft Expression 2 website. Live encoding, events, etc... Smart recompression, for example if you just edit some of the video, only the cut will be recompressed. Animations in XAML can be burnt inside the video. Closed captions. Improved Silverlight players, including a video gallery player. More options for interlaced content. .NET object model. Demo New codecs Aspect ratio is easier ......

#Mix08 evenings are pretty cool

So last night was the last evening for many (but not for me since I am flying only tomorrow, ha ha), and there was a number of dinners and parties going on. I was lucky to be invited to a great dinner at Zeffirino's thrown by IdentityMine. These dinners are always wonderful occasions to meet and talk to the big players in the field of WPF and Silverlight, designers and developers mixed. Yesterday was not an exception to that rule, with Scott Guthrie, Miguel Icaza (of Moonlight and Mono), Grant Hinkson ......

#MIX08 Session: Touch Me: Where Are Interfaces Going?

Cynergy.Labs, cool concept of "no touch gesture", with a "pinch" gesture to manipulate objects Challenges with Touch-based interfaces It's ambiguous. You're never sure where the next "touch" is going to be. Dominant hand plays a role in tactile interfaces "Now we can detect the shadow of the finger and know where it will land" Voice is going to be the next big move in user interface "Having a developer and a designer in a room is like having a humidifier and a de-humidifier in the same room" :) ......

MIX08: Keynote with Steve Ballmer and Guy Kawasaki (7)

  • Ballmer really knows his facts. First time I see him speak, I find him impressive. Better than last year's keynote with Ozzie, and I would even say better than 2006's keynote with Gates and O'Reilly

MIX08: Keynote with Steve Ballmer and Guy Kawasaki (6)

Ballmer: "Silverlight for iPhone is interesting, we want to have Silverlight everywhere" Ballmer "But I am not sure that Apple will welcome a royaltie-free, open platform running on their phone" Ballmer "All the relevant applications we have on the web will move to Silverlight" Woman from the floor "I love it that there are no bathrooms line here" Q&A from the floor is really going well. Ballmer did the monkey for web developers :) ......

MIX07 day 2

On Tuesday, most of the day was packed with sessions. I managed to see very interesting information. Microsoft is really pushing SIlverlight a lot, and while it's great news for web applications, I really hope that they will not release their effort on WPF. We're waiting for V2!! Building Silverlight Applications using .NET (Part 1 of 2) This session was most probably great for developers without experience with WPF. For me, however, after a certain point, I found myself thinking "I know all that ......

MIX day 1 (cont again)

I attended 3 sessions yesterday afternoon, all very interesting. MySpace megasite Quite interesting talk by the MySpace team about what strategies they are using to run, maintain and upgrade what must be one of trhe busiest website worldwide. The sheer volume of video, MP3 and pictures theys deliver simultanously is tremendous. And all that runs on ASP.NET and Microsoft platforms. Very impressive. They also developed their own tools for code management, allowing to release and if necessary rollback ......

MIX pictures on Flickr and on my PhotoAlbum

I just posted a bunch of pictures from yesterday on Flickr and on my PhotoAlbum. More pictures will follow shortly. Stay tuned.

MIX: Debugging remotely from VS2005 on a Mac!!

I know, I posted about this already, but this is so great it deserves a separate post: Using Visual Studio 2005, you can actually remotely attach to a Silverlight process running on a Mac, and debug!

Isn't that cross platform pushed to the max??

MIX: Day one review (morning)

Amazing day yesterday. It all started with a great breakfast set up by the Venetian team. They really do an amazing job. The hotel is just great, not only because it's so big and luxurious, but also because every details is taken care of, every detail is perfect. I had the same impression last year, impression confirmed. The key note was great, though to be fair last year's was better. Ray Ozzie just cannot beat Bill Gates, charisma wise. I was very happy to see Scott Guthrie on stage again, this ......

MIX: Silverlight streaming announced

One very exciting news: Microsoft is going to host up to 4GB of videos per person, free of charge. The tool Expression Media will allow very easy encoding of these videos in a format and quality compatible with Sliverlight. Once encoded, upload your video to the Microsoft site, and you get a URL which you can then embed in your website.

The nice things is that the videos are streamed, and this is supported natively by the SIlverlight engine.

MIX07 day 1 (cont)

The big news We were expecting a big news today, there are actually two: Silverlight will be able to run .NET. This was actually announced to us under NDA a few weeks ago. Here's a great opportunity to create service-enabled application on the web without JavaScript. Quote from Ray Ozzie: "Silverlight brings .NET to the Universal Web". Silverlight will have three pillars: Video, .NET and Services. Microsoft Expression shipped today! We heard rumors that this might be true, now it's confirmed! Congrats ......

MIX07 day 1

Getting started Breakfast was had (great buffet like last year, and the dining room is pretty impressive and huge!) Trying to recognize known faces, but no luck yet! I also registered and got my goodie bag. The notebook looks great, even nicer than last year (I am still using last year's one, actually, and the pen). Apparently the myspace.com gadget is a CD opener. Man, that's bad engineering! These CD cellophanes are actually so damn hard to open that someone has to come with a gadget! Wouldn't ......

MIX: Here I am

That was a LONG trip, but here I finally am. Check in went fine, the room is nice though less impressive than last year (well, last year I had, for some reason, received a huge suite). This year, I "just" got the "regular" suite in the Venezia tower. Seriously, the room is great. After check in and a long hot shower, since it was too late to register for the conference, I just went downstairs for a bite, and for a small walk in the casino. The energy here is amazing. I will register tomorrow morning, ......
