Yesterday, Stan, the founder of this blog, gave me a link to a project host on the Team Foundation Service (visual studio.com). I tried to connect to it with Visual Studio 2010. it simply refused to work.
After much annoyance, he asked me to try adding the TFS server to Visual Studio 2012 and it worked (Why didn’t I think of that?). Eventually I figured out that I needed to install the Visual Studio 2010 SP1 Team Foundation Server 2012 Compatibility GDR (KB2662296). Then I was able to add the solution to Visual Studio 2010. It seems there are several updates for Visual Studio 2010 SP1, some specifically dealing with Windows 8 compatibility. Unfortunately Windows update does not prompt me to install them. I will search for and install these tonight to prevent future issues.
