On experimenting with LINQ CTP without screwing up Visual Studio (C# only)

LINQ May 2006 CTP installs C# 3.0 compiler and new C# language service into Visual Studio 2005. New syntax, keywords, Intellisense for extension methods and all that jazz. This essensially disables native C# 2.0 compiler and C# language service. If you installed LINQ on Virtual PC - big deal. But if not and you want to switch C# back to 2.0 - there is a solution. Folder bin contains two little scripts called "Install C# IDE Support.vbs" and "Uninstall C# IDE Support.vbs". Just run latter one and your native C# 2.0 is back. Somehow there are only scripts for C#.
