Version Switching between 1.1 and Whidbey

I almost forgot to mention the handiest utility for anyone who installs the .NET 2.0 Framework: Denis Bauer's ASP.NET Version Switcher. Since it is simply a beautiful GUI for the command-line aspnet_regiis.exe utility, it works great for switching all your applications between 1.0, 1.1 and now 1.2x. Go get it!
