At our events I often hear questions about where to get the extensions for Visual Studio to work with the new framework. I went to the resources site (http://msdn.microsoft.com/events/resources) and from that page clicked on All Downloads. The chart below is copied from there. For the demos from the launch events, I've installed Visual Studio, and added the Extensions for WPF, WF and then also loaded the Expression Blend beta 1 on my machine. We are working on posting the code for the sample applications as well. I'll let you know when they are available.
