Thanks to everyone who attended!  Sorry about the demo hiccups / going over.  As I mentioned in the beginning, I had a hard time trying to get everything I wanted to cover into 90 minutes.  As you can see, there's quite a bit in the ASP.NET 3.5 Extensions.  Normally, I make all of my code demos available for download.  However, I used a newer build for my demos that's not publicly available.  Once we release the new bits, I will make my code available.  For now, you can download my ASP.NET 3.5 Extensions deck here.

UPDATE: I just created a list of links on my Windows Live Space called ASP.NET 3.5 Extensions.  This list has links to all the relevant landing pages & forums for the various technologies covered today.  Newer versions of MVC, Dynamic Data, and the Silverlight Controls have been released since the December 2007 release of the ASP.NET 3.5 Extension Preview.  Make sure you read the release notes of each newer package to understand how to get the newer bits working on top of the December 2007 preview.  The ADO.NET Entity Framework and ADO.NET Data Services in the December 2007 release of the ASP.NET 3.5 Extension Preview are the latest releases as of today (04/30/2008).  Stay tuned for a newer release that will reflect the updates you saw today.
