I presented at the Roanoke Code Camp 2008 a couple of weeks ago. I never got around to posting the slides and sample code. Here's the stuff for the .NET 3.5 Language Enhancements presentation I did. I didn't have slides or sample code for my Silverlight 101 presentation. It was all hands on using the DLRConsole and experimentation in Visual Studio 2008. Enjoy.
