Visual Studio 2010 won't save TFS as current source control plugin?

I'm configuring VS.Net 2010 on a new Win7 PC to connect to a Team Foundation Server repository. After selecting Team F开发者_C百科oundation Server as the current source control plugin under Tools -> Options, VS.Net keeps switching back to "None".

If I choose TFS, click Ok, and immediately open a solution that uses TFS, VS.Net says it can't contact source control and asks if I want to temporarily work unbound. The odd thing is that every few tries everything works, and I can work connected to TFS.

If I choose TFS, click OK, and immediately go back into Tools->Options, 2 out of 3 times "None" will be selected as the source control provider.

Also tried running VS.Net with and without admin privileges, with same results.

This issue was caused by legacy source control bindings still present in the .csproj and .sln files, left in place after the project was imported from VSS to TFS. I didn't have VSS installed on my system, which is why I got this error (the VSS provider couldn't be found). To resolve, you should unbind the project from the legacy source provider when prompted, and then rebind to TFS using File -> Source Control -> Change Source Control.

In my case, I had to start VS2010 in safe mode

devenv.exe /safemode

Run the above command in a command prompt. That should start VS2010 without any plugin enabled. Then go into Tools > Options and choose your Source Control (eg: TFS or any other) and click OK. That should solve the hassle.
