Help! Can't open any VS.NET projects!
I've tried everything.. repaired my VS.NET install, uninstalled, reinstalled, removed every plugin, it still gives the same message every time I open a C# project:

---------------------------
Microsoft Development Environment
---------------------------
The application for project 'C:\Source\SharePointFav_trunk\ClassLibrary\SharePointFav.ClassLibrary.csproj' is not installed.
Make sure the application for the project type (.csproj) is installed.
---------------------------
OK
---------------------------
I've Googled extensively and in every case that I found a workable solution the reason for the error was that the user hadn't installed C# on the Visual Studio install. I definitely have C# installed here.
I installed AnkhSVN 0.4.1 just before I started receiving this error. Uninstalling AnkhSVN didn't solve the problem.
Please, if anyone has any information that can help me, leave a comment below or email me (steve@infotechcanada.com).

As a follow-up to this story, my "solution" to the problem was to reformat my computer. Sorry I don't have better news.
