Coding4Fun - Introduction to Silverlight and WPF Pixel Shaders

My new article for Microsoft's Coding4Fun site is live. It's my second article for Coding4Fun after my first Silverlight Face Detection article. The article explains how to write pixel shaders for Silverlight and WPF, what tools should be used, and how to work with the tools. Furthermore, it shows how to build an extensible Silverlight shader application with the help of the Managed Extensibility Framework (MEF)
The application not only comes with the two shaders that are implemented in the article, it also contains three other shaders I’ve written before. The complete source code is licensed under the Ms-PL and can be downloaded from the CodePlex site.
