I installed Visual Studio 2012 and at a later date Update 2. After installing Update 2, when I load any project, I get the following error:
I had a similar error. After I updated to VS2012.U2, the problem went away. TFS 2012 update 2 can't be removed without removing TFS. While I had an issue with upgrading from TFS2012.U1 to U2, I have found TFS2012.U2 to be worthwhile.
