When browsing through the documentation for Beta 1 on MSDN I found that there's also a nice training-kit available here.
The training-kit includes presentations, demos and labs on the following:
- C# 4.0
- Visual Basic 10
- Parallel Extensions
- Windows Communication Foundation
- Windows Workflow
- Windows Presentation Foundation
- ASP.NET 4
- Entity Framework
- ADO.NET Data Services
- Managed Extensibility Framework
- Visual Studio Team System
Unfortunately not so much content on VSTS, but still lots of other goodness...
