I just did a clean install of TFS Update 2 CTP 4. Added a small test project and checked it into source control. As soon as I do a history on those files by right clicking in Source Control Explorer I am getting error TF10158. I have been struggling with this error in various places in TFS 2012 RTM and was hoping this would be fixed for Update 2.
My company uses AD displaynames that contain commas. for example "Smith, John".
This particular instance of the error which is occurring using the "View History" command from the Source Control Explorer context menu was not happening in RTM version.
The TF.exe History command line is working okay.
see attached screen shot.
