Delete all files from the following folders and try again:

Okay, so I figured it out. I had to delete everything in this directory: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\

Answer 4

If you think your GAC has become corrupted, I suppose you could take a look at the DLL in there. I bet you could find a checksum for the dll online, or re-download it. I'd follow Reed's advice, though -- that seems more likely to treat the root issue.

Answer 5

Have you tried starting devenv in safemode?

devenv.exe /SafeMode

If this works you can try resetting the settings files to:

devenv.exe /ResetSettings

Instead of repairing Visual Studio you reset the user data back to their defaults with:

devenv.exe /resetuserdata
