So you may be asking, “What is it doing in Silverlight 5?” Developers have realized for a long time that things like 3D Graphics inside of a web browser would be beneficial for many applications including : medical, transportation, government and of course gaming. They requested the feature using Microsoft’s UserVoice and Microsoft added it as part of Silverlight 5. Silverlight 5 implementation of 3D is the most powerful yet running inside of a web browser.

Now that we know a little more about XNA, let’s get started…
