Here’s something that might help you. It’s the TeamReview addin recompiled to work with Visual Studio 2012. I take no credit whatsoever other than the small changes to make it work. The original code can be found at: http://teamreview.codeplex.com/.
You can download it right now from here: TeamReview.VS11. I will try in mean time to push the code to codeplex in it’s rightful place
