I have recently upgraded the TFS Administrators Toolkit to Visual Studio 2012. It's now released at Visual Studio Gallery under the exiting name TFS Administrators Toolkit for VS2012.
The Visual Studio 2012 version uses the TFS 2012 object model and integrates directly into the new Team Explorer and in the "new" Team Explorer Home dropdown.
Apart from the technical modifications there is no new functionality in this release. The 2010 version remains unchanged .
You can find the different versions at
- VS 2010
- VS 2012
