tfs - Visual Studio 2010 crashes on startup

Question

We have been using vs 2010 for years on this machine, (server 2003) and now visual studio just started crashing on startup. there is no way to run it at all, it just crashes every time.

I've tried Devenv.exe /SafeMode, resetsettings, etc. same result. I've tried re-installing vs2010, I've tried un-installing it and re-installing, same thing.

The event log says it's to do with team foundation server:

---

EventType clr20r3, P1 devenv.exe, P2 10.0.30319.1, P3 4ba1fab3, P4 microsoft.teamfoundation.common, P5 10.0.0.0, P6 502e379e, P7 4b6, P8 45, P9 system.missingmethodexception, P10 NIL.

There is also an error with stack trace:

We do use TFS and have had no problems with it.
Any ideas as to why this started happening, and more importantly, how can I fix this? there does not appear to be any way to start visual studio without the tfs component, and we need tfs anyway.

Answer 1

Following worked for me

1. Close all instances of VS

2. go to [System Drive]:Users[User Name]AppDataRoamingMicrosoftVisualStudio10.0

3. delete all the files and folders from the above folder.

and reopen the VS and everything should be back to normal.
