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. However, the CommonServiceLocator does not exist for all MVVM Light-supported frameworks. We have the following situation: WPF3.5 SP1, WPF4, WPF4.5: Depends on the CommonServiceLocator Nuget package. Silverlight 4, Silverlight 5: Depends on the CommonServiceLocator ......

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 ......

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 ......

#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. Upgrade Upgrading the installations should not require an ununistall, so try to simply run the MSI downloaded ......

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). More information about Nuget and MVVM Light. Scroll down to have a chance to win a copy of Expression Studio V4! MVVM Light started its “career” on Codeplex in October 2009. Back then it was intended ......

#mvvmlight V4RC available on #nuget

I just published the MVVM Light V4 RC packages to Nuget. Note that this is still technically a preview, so the main package is still V3. The V4 packages are available here: Package with libraries and content: When you install this package into a “virgin” application (i.e. an application without ViewModelLocator, preferably a brand new application), it installs a new ViewModel folder with a MainViewModel, ViewModelLocator and adds an entry into the App.xaml file to intialize a the ViewModelLocator ......

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.

More details here. Sorry about the confusion people!

Slides and source code for my past talks this year

I had the chance to be invited to talk at various conferences this year already, and I promised to post the slides and source code, so here it is! MVVM Applied: From Silverlight to Windows Phone to Windows 8 Belgium, Netherlands, Bulgaria The Model-View-View Model pattern is a common denominator between applications using XAML to create the user interface. First applied in WPF, it was then easily ported to Silverlight and Windows Phone development. With WinRT and the Metro-style applications, XAML ......

Impressions, slides and code from TechDays Belgium and Netherlands

Update: Posted the video of “MVVM Applied” below. This week I was “on tour” in Belgium and Netherlands and presented 3 times: “MVVM Applied, From Silverlight to Windows Phone to Windows 8” (in Belgium and Netherlands) The goal of this session was to make people feel confident that the skills they acquired working in various XAML frameworks (Silverlight, Windows Phone, WPF, Surface, etc) are going to help them tremendously when developing Windows 8 applications. It was a session packed with code, ......

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. I had a few surprises with this build. For example from time to time, the new “Metro style applications” just cannot be launched anymore. Nothing that a simple reboot cannot fix… but I’ll come back to that in a moment. A couple of ......

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. How do I know if I have the bug? Check the Programs and Features control panel, and look for MVVM Light. If the “Version” column shows 3.0.2.19, you have the bug. If it shows anything higher, you don’t. For instance, the new version with the bug correction is 3.0.3.19. Also, any version ......

MVVM Light for Silverlight 5 is on Codeplex #mvvmlight

Here we go! After the Microsoft team released version 5 of Silverlight yesterday, MVVM Light is available for this version of the framework too. I did not create the installer yet (that will take a few more days), but you can download the source code and build it yourself easily. Source code on Codeplex. Instructions to build the code. With this latest release, this puts the number of supported frameworks to 8: .NET 3.5 SP1, .NET 4, Silverlight 3, Silverlight 4, Silverlight 5, Windows Phone 7.0, ......

Silverlight 5 is released!

Microsoft just released the version 5 of Silverlight! It’s a great news and I really want to congratulate the whole team on this impressive collective effort. The official announcement is on the Silverlight team blog! The purpose of this article is not to be exhaustive about the list of features (there have been, and will be, many more very detailed articles such as this series on the Silverlight blog) but rather to explain why this version in particular makes me happy to be a Silverlight developer ......
