Expression Blend for Developers

On April 28th I was given the opportunity to speak at the Microsoft DevDays in The Hague in the Netherlands. My session about Expression Blend for Developers was chosen by the community to fill one of the Wildcard slots. The idea for this session came when I saw a coworker tinker with XAML in visual studio to create an animation when he had Expression Blend available through his MSDN subscription. It turned out that a lot of Silverlight, WPF and Windows Phone 7 developers didn’t know they could use Expression Blend. “Expression Blend is for designers”, they thought. The first…


First Windows Phone 7 Application

Duck’n’Cow My first Windows Phone 7 application is available in the marketplace, Duck’n’Cow. Feel free to download and play with it (and rate it of course ). I build the application to try some of the features of the Windows Phone. In this application I focused mainly on the accelerometers. The application shows a Duck and a Cow, hidden in a circle. When you shake the phone the duck pops up and you hear it quack. When you turn the phone upside down, you’ll see the cow pop up. Idea I wanted to create a funny looking application that could…

Customizing Silverlight properties for Visual Designers

When building custom or user controls you probably end up with a large amount of properties on that control. When using the control in a visual designer like Blend or the Visual Studio designer these properties just show up. Adding a bit of structure in this can be done very easily by adding a couple of attributes to the properties. The attributes to let the visual design know what to do can be found in the System.ComponentModel namespace. There’s a WPF version of this namespace also. For the sake of simplicity I’ve created a UserControl and set the background color…

Unit testing MVVM in Silverlight – SDN Event–Code and Slides

Yesterday I gave a talk at the SDN Event in Zeist about Unit testing MVVM in Silverlight. I talked briefly about how MVVM works in Silverlight and dove deeper into the Unit Testing Framework which is available in the Silverlight Toolkit. After going through the various attributes used in the framework I gave a demonstration on how to use StatLight, a command line tool for running tests. I would like to thank anyone who attended my session for coming and SDN for organizing and hosting this great and informative day. Slides Code

.NET, Silverlight, Visual Studio


If you often use open source libraries you probably have a large library with various tools, like I do. NuGet is an extension for visual studio that enables you to install, uninstall and upgrade open source packages into your application very easily. Say for example you want to use MvvmLight or Ninject in your project, with NuGet it’s nothing more that tell it to add the package to your project. NuGet NuGet (formerly known as NuPack) is a free, open source developer focused package management system for the .NET platform. You can download the .vsix extension at After installing…
