Hay gang,

Recently I started using VS 2010 (.NET 4.0). I opened a copy of a VS 2008 (3.5) project in VS 2010 and walked through the upgrade wizard. (By the way, make your own backup, and don't let the wizard do it. Cause the compiler to get confused.) Anyway, Everything went smoothly. I thought. But when I started to try and use something new namespaces that came with .NET 4.0, all the dialog (namely Add Reference) still indicate the project is a .NET 3.5. Can someone please point me some documentation describing how to truly change the project to be a 4.0 project.
