We have had a good response to the free 8 module Silverlight Training Kit we released on Channel 9 back at MIX and that Scott Guthrie announced. We have since updated at the Silverlight 4 Launch with some new content and fixes. We’ve also found 2 issues since then that you might run across. I’ve corrected these in the source and will update them on the Channel 9 site in our next round (which I hope to include VB version of the courseware, too!)
You can use the 8 modules, 25 videos, and several hands on labs online or offline from links on the Channel 9 site. I’ve included a breakdown and links to all of the content here in this post. The key to this training material is not the features it covers (though it covers a variety of topics including the features in this cloud) but rather that it teaches from the perspective of building a business application.
