Comments Check-In Policy with Visual Studio 2012 and git-tfs

Once upon a time, the “Require a Changeset Comments” check-in policy for TFS came in the TFS Power Tools. In Visual Studio 2012, they rolled that policy into the Visual Studio distribution. Now, the check-in tool from git-tfs cannot find it. To solve that problem, you need to make the check-in policy available to git-tfs.

Copy Microsoft.TeamFoundation.VersionControl.Controls.dll from

C:\Program Files (x86)
  Microsoft Visual Studio 11.0
    Common7
      IDE
        CommonExtensions
          Microsoft
            TeamFoundation
              Team Explorer

to your git-tfs installation directory. That should allow the check-in tool to find the policy.
