Internal error in Changeset Comments Policy after updating VS2015 to Update 1

Okay, i got it. Somehow the installation messed something up. On my machine the folder

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation

was pretty empty, where my colleagues had a junction there, leading to this folder

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\XXXXXXX

where XXXXXX obviously varies from machine to machine. To find the correct one, go to the extensions folder (one up) and look for the one that contains "Microsoft.TeamFoundation.Build.Controls.dll" and some other Teamfoundation dlls, then open an elevated command prompt and create the missing junction like so:

mklink /j "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer" "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\XXXXXX"

(watch out, you need to replace the XXXXX with the folder name on your machine)

- NOTE: Please dont forget to RESTART Visual Studio after doing this change in order to start cheking in seamlessly.
