If you try to create a new team project in the Beta version of the new Team Foundation Server 11 (and/or RC,RTM 2012) using Visual Studio 2010 you will get following error:
TF30172: You do not have permission to create a new team project.
Even if you have set the permissions and you are eligible to create such a project you will get the error. The only solution until now is using the new version of Visual Studio 2012 RC to create a new team project with.
With Team Foundation Server 2012 RC and RTM the error is as follows:
TF30172: You are trying to create a team project either without required permissions or with an older version of Team Explorer. Contact your project administrator to check your permissions or to determine how to upgrade Team Explorer.
