Lutz Roeder's C# Silverlight Samples
Lutz Roeder, of Reflector fame, has created 3 Silverlight sample apps written in managed code and hosted them on his site. The first is a Boulderdash game clone, the second is a clean mp3 player UI and the third is a scripted sound and graphics demo. Click the images below to run the samples. Source for each can be found on Lutz's Silverlight page.
