What's New in .NET 3.5 and VS 2008

In preparation for the Install Fest I am putting together some demos for the .NET users group on some of the new features in .NET 3.5 and Visual Studio 2008. I am sure Jason or Mithun will be providing some slides and presentation from Microsoft, I am just putting together some notes from my last 6 months of working with the betas and the final release. I will add notes as I find interesting things.
