This is a great new project!  This is a DNN 5.1.4 CE install.  I uploaded Michael Washington’s great Silverlight module and then followed his tutorial here.   It took me a bit to get my arms around how the module was interacting with DNN.  I’ve listened to Michael give amazing talks on Silverlight.  After I played around with Expression Blend and VS2008, I realized that it’s just like inserting a CSS file inside of an html page.  DNN does the heavy lifting and Silverlight can sit on top in it’s own sandbox. Very cool indeed.
