Microsoft has recently released an updated training kit with presentations, hands-on labs, demos and event materials describing features found in .NET 3.5 SP1 and Visual Studio 2008 SP1. Here you will find over 100 MB of information with tips on using MVC, Ajax, the Entity Framework, Visual Studio 2008 SP1 and other tools. Materials used world wide in the .NET 3.5 SP1 training tour are also included. You can read more details here. In the download section shown below, I also include a link to the VS 2008 training kit released last Fall.
