This may be a possible answer for the problem.
Some from the answer:
- Check which files were changed (why and how) after update from a source control engine
- Review the list of extensions and plugins. Try to disable all or some of them
- Close Visual Studio and kill all the development processes:
devenv, mspdbsrv, vcpkgsrv, msbuild, msvsmon, vshub, vstestetc - Remove
.suo, .ncb, .VC.db, .VC.VC.opendbfiles of the solution as well as.vsdirectory, which sometimes cause problems - Remove project setting files, sort of
YourProjectName.vcproj.DOMAINNAME.LOGINNAME.userorYourProjectName.csproj.user. The setting file name depends on a project kind you use - Run
"C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /setupor"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /setupfor x64 environment
