Thanks to everyone who attended. Sorry about the audio difficulties. Unfortunately, there isn't much I can do once the webcast starts. The deck is here. The code is here.
You will need Microsoft Silverlight 1.1 Alpha Refresh, Visual Studio 2008 Beta 2, Microsoft Silverlight Tools Alpha Refresh for Visual Studio (July 2007) , Microsoft ASP.NET Futures (July 2007). There are links to download all four from http://silverlight.net/GetStarted/. There are links for the Expression tools as well.
If you missed the webcast, you can watch the recording here.
