I recently downloaded the VS2008 beta 2 release. It works well so far, runs very smoothly on Vista and looks a little prettier than VS2005. So that I could combine playing with VS2008 and playing with Xna I knocked up a Xna Windows Game project template similar to the one available in Xna GSE. It sets up references to the Xna assemblies and has a little custom MSBuild lovelyness to enable building content (but see notes on the download page). You can download the template here:
