[Team System] How to Delete a TFS Team Project

There are several ways to delete a TFS team project, but not via the Team Explorer. Steven Smith writes:

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

Julien Lavigne got a utility which does the same thing via a web service.
