I deleted a project in Team Explorer without problem. I then went to Source Control Explorer to delete the project's folder. I get: "TF10169: Unspported pending change attempted on team project folder $/Test. Use the Project
Creation Wizard in Team Explorer to create a project or the Team Project deletion tool to delete one."
You can delete the project using the TFSDeleteProject.exe tool found under [C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE] . You can find more information on the parameters of the tool here : http://msdn.microsoft.com/en-us/library/ms181482.aspx .
