I recently created a DLL and I wanted to reference it from a project I was developing in Visual Studio. In previous versions of Windows, doing so was simply a matter of dropping the DLL file in the C:\Windows\assembly folder. That would add the DLL to the Global Assembly Cache (GAC) and make it accessible in Visual Studio. However, as is often the case, Window 7 is different. Even if you have Administrator privileges on your machine, you still do not have permission to drop a file in the assembly ...
This is Easter weekend, and the end of the school year is looming closer! Our developer sessions at WashU end today. Students will turn their spare time focus to finals and getting home for the summer. Over this short course of time, we’ve had a bit over 50 students show some level of interest in developing apps for Windows Phone. Currently the total apps submitted by students is approaching about 20. Several students have received new phones as part of their agreement to submit applications ...
Hello folks, Recently I got involved in a project for building a demo application for one of our customers with Kinect for Windows. Yes, something similar what Tom Cruise did in the movie Minority Report. Waving arms, moving stuff around, swipes, speech recognition, manipulating computer screens without even touching it. Pretty cool!!! The idea in the movie showed us how technology would be after 50 years from that day. Minority Report Movie clip. Well, that 50 years of time frame got squeezed and ...
Forward: Sometimes I really feel like technology recruiters have no experience or knowledge of the field they are recruting for. A warning to those companies hiring technical recruiters -- ensure that the technical recruiters you hire to fill a position are actually technical. Here's proof below, where I make up completely ridiculous technologies, but still have interest from the recruiter for an interview. Letter to me: Hello - Your name came up as a possible match for a long term contract Cold ...
We are almost done everything about the WCF transport extension over the message bus, which makes our services can be scaled out by introducing more instances over machines and servers. We had finished the structure of our transport extension and implemented the request reply mode in the 2nd post, the datagram and duplex mode in the 4th and 5th post. As I have said at the end of the 5th post, currently we can use our transport extension. But there still something left. Although are not that major ...
Eric Ligman, from Microsoft, posted a great blog post this week listing all of the SharePoint 2010 Virtual Labs that are available from Microsoft. His blog entry is here: http://blogs.msdn.com/b/mss... He also posted other resources as well. I’ve copied his Virtual Lab links here: SharePoint Server 2010 Virtual Labs MSDN Virtual Lab: SharePoint Server 2010: Introduction ...
The Problem I got a compilation error in my ASP.NET MVC3 project that tested my sanity today. (As always, names are changed to protect the innocent) The type or namespace name 'FishViewModel' does not exist in the namespace 'Company.Product.Applicatio... (are you missing an assembly reference?) Sure looks easy! There must be something in the project referring to a FishViewModel. The Confusing Part The first thing I noticed was the that error was occuring in a folder clearly not in my project ...
If you have not heard the latest technical news yet, the SQL Server 2012 Virtual Launch event is today March 8, 2012! Register to not to miss this opportunity to interact with technology experts and win cool prizes! I am thrilled and excited! Why? Because like in the automotive industry, every new iteration of a vehicle is more fuel efficient, safer, more polished, looking more attractive and fun to drive. Sure, the the new version of the SQL Server is ready to take me further in what I can deliver ...
Applied WPF 4 in Context (http://www.apress.com/9781... starts with a simple introduction to WPF and then shows a complete WPF application from sketch to completed code. This APress web site states "This book can be used by a junior developer to learn WPF and understand how to architect a layered application, and it can also be used by a senior developer as a reference for developing scalable WPF applications. " - this summerises the book very effectively as it is indeed an excellent book ...
When the Space Shuttle was developed so many years ago, it was just the first step in developing a re-usable launch system. Regrettably this further development never took place, however plans are now afoot to produce a super jumbo jet to act as a re-usable first stage. Launching rockets into space from aircraft has been done before, but this is the first on this scale. Source: SPACE.com: All about our solar system, outer space and exploration ...
In this post we will see few of the initial steps for developing BizTalk Solutions for integrating with PeopleSoft Enterprise Systems using PeopleSoft Adapter. In order to proceed further, you must have Installed and Configured PeopleSoft Adapter properly, both on BizTalk side and PeopleSoft System side. This particular post is based on PeopleSoft HRMS 9.0 system. But the steps shown below should be same for any PeopleSoft Enterprise System. The steps will be same to connect to any Component Interface ...

Update: Posted the video of “MVVM Applied” below.

This week I was “on tour” in Belgium and Netherlands and presented 3 times:

As I was working on “The Developers Guide to AppFabric” e-book I also started developing a training course on the Azure Service Bus. The first delivery of this course is scheduled for May 3-4 in Stockholm. I’m really looking forward to delivering this, it will be exciting to be working with emerging technologies. The course will be updated on regular bases to cover the new features as they pass through CTP and into release. The course details are here. If you have any questions about the course, ...
I ran across a unique scenario recently, and I’m not sure if I should be proud of the solution, or appalled at the Frankenstein result. Either way, I thought I’d post about it to possibly help others in the same situation. I was developing a website leveraging jQuery / AJAX to query views of data at runtime. The kicker? I didn’t know which views. The choice of database view was determined via configuration and user choice. I was leveraging jqGrid for the client-side grid presentation, sorting, filtering, ...
Intuit Partner Platform and Data Access I’m going to make some assumptions that will cover a lot of folks developing applications to work with QuickBooks. 1. You are running a copy of QuickBooks on your development machine. 2. You are running Visual Studio 2010 as your development environment of choice. 3. You have some flavor of Microsoft LightSwitch installed. 4. You want to access QuickBooks data on your machine to USE LightSwitch. Well now you have an option. Head on over to http://www.rssbus.com ...
Most of us spend our time in Visual Studio writing .NET code within a Visual Studio solution. Given this situation we find it very easy to integrate with Team Foundation Server for our source control and have a well known work pattern. But what happens when you want to use TFS as source control for non-Microsoft development? The most important thing to remember is that source control should be as transparent as possible to the developer. If the particular language or product does not have an Integrated ...
I am happy to announce that I have open sourced and released my first Windows Phone 7 Application to Marketplace a few days back. You can get the source code from http://gtasksplus.codeplex.... I will also do a series of few blog posts to take you all through developing the application from scratch. Check back regularly. Sorry for not posting anything for a long time, I have been concentrating on learning some new things and did not really get a chance to continue blogging. Will try and be consistent ...
In this article, I will show you some tips to improve your ASP.NET performance. 1. Disable the Debug Mode or Set Debug =”false”How it affect performance: By default this attribute is "true" when you create new application and is useful when you are developing the application. Debug = true means that pdb information to be inserted into file and this results a larger file size and it's performance issue. Before deployment you should set the following tag <compilation defaultLanguage="Vb" debug="false"> ...
An interesting discussion popped up on Twitter between myself, Steve Rogalsky, Terry Bunio, Mike Iwasiow, David Alpert, and some others around using hours as a software estimating unit of measure. Steve’s been reading the book Beyond the Goal by Eliyahu M. Goldratt and blogged about his stance on using hours for sizing work items. In a nutshell Goldratt offers the following arguments: Asking someone for a timeframe to complete a task puts their image in jeopardy PMs will always try to squeeze whatever ...
Command passing is a handy way to execute pieces of code on specific threads. The idea is simple enough: Write a command into a buffer and that command then gets executed on some specific thread that monitors that command buffer. This paradigm is used in graphics APIs like DirectX and OpenGL, for instance. This allows you to split your data into working sets that are owned by a single thread and must maintain their state over a specified time period. In the graphics engine I’m developing at Raccoon ...
Apart from the Introduction that I gave from my previous blog posts about the book and the Windows Phone 7.5 Development, I think we have to jump into the technology of it. In this post we are going to talk about the Design Language, Real Estate, Input Patterns. Design Language: Design Language in my view is something that first strikes to the user/developer when they think of the application usage/development. How you want to design your application or how they users react with the navigation screens/patters ...
I wanted to introduce to you all to a wonderful book that I came across recently by, Shawn Wildermuth “Essential Windows Phone 7.5 Application Development with Silverlight”. I never bought a text book but I decided to buy this and start reading it, as I was going thru the book I decided that I made a good buy here. This book is very easy to read and a very good place to start developing Applications for Window Phone 7.5 with Silverlight. This series of blog posts are going to be on just Windows Phone ...
In my quest to improve speed with developing software I have been investigating how to put as much as possible to the keyboard. This has opened a world of shortcuts. Today I thought I would blog about the top 5 shortcuts that I didn’t know about before that I have found useful. These are shortcuts that I haven’t seen to many people use, see how many you know… 1… Selects the Address Bar Alt + D Most useful when you are in a Web Browser and want to change the url address. 2… Move active window to other ...
2011 has been a fantastic year for so many different reasons, and its laid the groundwork for a fantastic 2012 to come! Online Business Systems In February I started with Online Business Systems, a technology and business consulting company based out of Winnipeg, Manitoba but with offices in Calgary, Edmonton, Portland, Minneapolis, and Toronto. Coming to online was the best decision I’ve ever made in my career. The mentorship and nurturing, the opportunities and support, and the culture of the organization ...
I would like to share with you some exciting news from the Gizmox labs. If you haven't heard by now the Visual WebGui Mobile Team @ Gizmox has been working on a .NET Mobile Framework for a few months now. This mobile dedicated framework continues the Visual WebGui vision towards the mobile development workd by enabling Microsoft core .NET developers to leverage their existing skills for developing cross-platform HTML5-based mobile apps within Visual Studio. As with its Web Framework, the Visual WebGui ...
To me the answer of whether or not you need version control is simple - do you have users? If the answer is yes, then you need version control. Note that "version control" is not the same as "source control". Source control refers to maintaining history of your source code. Version control (also known as "configuration control" or "configuration management") is more than that. Version control, as its name indicates, means tracking versions of your software. The best way to illustrate the purpose ...
A friend of mine works for a large bank… about a year and a half ago they needed a new system developed for their division. They went through the normal process of using one of the recommended service providers to develop the system and this was their experience, which is still typical with most institutions I know… For the first few months development of the system seemed to be progressing along fine. They had meetings, business analysts put things on paper and the developers nodded their heads ...

As someone who works a lot on Silverlight and as someone who have presented lots of trainings / talks over Silverlight; i am been getting a lot of questions based on future of Silverlight. Is Silverlight dead? http://www.zdnet.com/blog/m... These are often from end-clients, managers, architects or even consumers. Sometimes also from guys who have little exposure to Silverlight; but still want to engage in the conversation as it is "happening" ...

I am not the fastest typist… I know it. Up till about a year ago I was a two finger typist and my two fingers could fly over the keyboard doing all sorts of acrobatics getting me up to a whopping 30 odd words per minute. Not bad for two fingers but barely close to some of my friends who speed away at 90+ words a minute using both hands. So it bugged me…. I mean I would like to consider myself a professional developer and feel that if I will be typing most of days then I should at least be doing it ...
This was a very interesting event, I had never spoken in an event with so many developers in one place. It was cool! I had two talks, one on HTML5 and IE9 where I demonstrated the HTML5 and CSS3 coverage in IE9 and performance improvements, the second on ASP.NET MVC Best Practices where I talked about a fraction of things that you need to be aware of and possibly use when you are developing an MVC application. The HTML5 and IE9 talk was more of a showcase and focused on new features that will continue ...

Furthermore she also expressed the benefit that it is providing to the citizen. Through the rest of the morning the news around TUO is being presented by Lyn and Matt Briggs across radio and TV. Tell Us Once is the major project Solidsoft have been developing on behalf of DWP. ...
On November 28th, 2011 I had the opportunity to give a presentation at the St. Louis .NET User Group on my experiences developing software for the Windows Azure and SQL Azure platform. Having been at PDC in 2009 for the announcement of Azure and been able to work on a number of Azure projects since that time I frequently see many Azure talks that are either: A) too high level and marketing oriented as they never tell you anything important or B) too low level and focused on a specific feature that ...
Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtension... /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\Web... ...
Problem Our global Jenkins continuous integration server throws this error during compile step. My local TeamCity continuous integration server runs fine. What is the difference. Background I integrate some static code analysis steps via MSBuild-targets in the csproj files. To allow a fast developing without a code analysis for ever compiling I bound these targets only to RELEASE-configuration. With the MSBuild element <ImportGroup> only one condition must be specified. So my construct was: ...
For good or bad, Microsoft’s Entity Framework (EF) has become one of the most widely used ORM tools out there. While some may state that it's not among the better ones (or that it's not even a real ORM), it’s definitely the most convenient one: its Visual Studio integration and consequently its integration with the MS SQL Server database is unparalleled. This is especially relevant to people who haven’t used the concept of object-relational mapping before - there's almost no initial learning curve ...
The Distinguished Field is often seen as the weaker of the two types of Fields when handling Fields in BizTalk. After all, the Distinguished Field can’t be used as a filter on a message, and it’s slower than its big brother the Promoted Field. Well, today I’m here to dispel the myth of the wimpy Distinguished Field and place in the pantheon of power that equals, and in some ways exceeds the Promoted Field. MYTH: Getting the value of a Distinguished Field requires loading the entire message into memory. ...

Introduction I’m sure by now you have heard that the Kinect SDK has been released by Microsoft. I recently had a chance to Guest Blog for the Microsoft MVP Award Program Blog on “Getting the Most out of the Kinect SDK”. Now before we get started learning about it, let’s look at what it is: *Kinect for Xbox 360, or simply Kinect (originally known by the code name Project Natal),[8] is a motion sensing input device by Microsoft for the Xbox 360 video game console. Based around a webcam-style add-on ...
During the last months, I was (for some reasons that are not related to programming) working for a dev shop where software development was done the 'traditional' way: You just write your application's production code, do it as good as you can, and hopefully it will be good enough and no problems will occur in production (this is HDD: Hope-driven development). Anyway, after I had finished this contract, I felt the need to review some core aspects of what I think is Test-driven development. And while ...
In the previous blog post I discussed working with the list import tool for creating lists which was a timesaver for developing lists in the UI and then importing that list into a Visual Studio solution. I had some time in-between projects to make this process for simple lists just using the default views. How about doing this entire process in about 15 minutes in code! This is such a time saver that I just had to blog about it and save other developers this time intensive task! 1. Use a utilities ...
Motivation During programming suddenly this error (“Failure has occurred while loading a type”) was thrown by accessing a artifact of a referenced library. In such cases I take the assembly fusion logger fuslogvw to search for problems of loading assemblies. Sometimes an old version from a not expected folder is binded. But all bindings were correct. Problem After several hour I got the right hint. Because the assembly is a COM+ one, there are some registration things in die background – and I don’t ...
Introduction In case you missed it, I have a 10-part series on Silverlight 5 on SilverlightShow.net. In this extensive guide to Silverlight 5, I give a step-by-step introduction to Silverlight 5, and dives into the features most important to a Silverlight developer. You can check out the first 3 parts now and I will be adding a new one each week. The Roadmap for this Series I’ve included the Roadmap for the series below as you may want to visit other sections as you learn Silverlight 5. I picked ...
I have been developing an MVC3 application with the intention of deploying to the Cloud. It was configured to use Forms Authentication with SQL Membership on SQL Azure. Everything seemed to be working perfectly locally, but after I deployed the Membership.ValidateUser no longer seemed to work. I could use the Providers to get information from the database (e.g. Membership.GetUser would return an existing account) which meant the database connection was fine and user existed, just the validation failed. ...
Everyone, Thursday, all day there is an MSDN webcast on building Windows Phone 7.5 apps. If you haven’t tried your hand at developing for the WP platform, I highly recommend watching this either live, or when they become available as individual streaming downloads. You may not own a Windows Phone, and that’s cool and all, but being a .NET developer puts you in a great spot to make applications or games that can reach millions. The great part is, if you don’t have a phone, YOU DON’T NEED ONE to write ...
