Team System Delete Project
If you need to delete a Team System Project you need to do it through a command line utility that is installed with Team Explorer. In my case, I created a test project but wanted to also test project deletion. There is no way to delete a project from Team System except through the command line tool, TFSDeleteProject.exe. This utility is in the c:\program files\Microsoft Visual Studio 8\Common7\IDE\ folder by default. To delete a project, use the following syntax:
TFSDeleteProject /server:ServerName ProjectName
Optionally, you can use /force to force the removal even if some pieces are locked, but this is not recommended except as a last resort since any locked components would likely be left behind and unremovable.
In my case, running this command resulted in the following output:
