We recently upgraded our TFS server to 2012 but due to hardware limitations I am still on VSTS 2010 pro with the 2012 compatability patch applied.
When I make modifications to work item type of Bug. I am getting the the following error message:
Failed to save the 'Bug" Work Item Type to the server.
TF223006: You cannot modify the definition of a work item tracking object with your version of command-line tools as they are not compatible with the Web services for Team Foundation Server. Contact your system administrator
to determine how to upgrade your installation of Team Explorer to a version compatible with Team Foundation Server
Thank you for an help,
Mike
