We have just released the .NET 3.5 Enhancements toolkit.
The .NET 3.5 Enhancements Training kit builds on the success of the Visual Studio 2008 Training Kit and provides developers with information on ADO.NET Data Services, ADO.NET Entity Framework, ASP.NET AJAX History, ASP.NET Dynamic Data, ASP.NET MVC and ASP.NET Silverlight controls.
Currently, the training kit contains six hands-on labs, made up of the following technologies:
1) ADO.NET Data Services
2) ADO.NET Entity Framework
3) ASP.NET AJAX History
4) ASP.NET Dynamic Data
5) ASP.NET MVC
6) ASP.NET Silverlight controls
If you leave feedback, we would be happy to place this into future releases which contain additional content, including presentations, demo scripts and screencasts.
You can download the training kit at http://go.microsoft.com/?linkid=8719735
The next iterative release of the kit will occur in sync with the beta release of .NET 3.5 SP1.
