Delete a project from Team Foundation Service

Since the "Team Foundation Service" hasn't an administrative console, it's not possible to use it to delete a hosted project.

So to delete a team project from one Team Foundation Service collection you have to use the "tfsdeleteproject.exe" command line tool:

tfsdeleteproject /collection:https://<your collection>.VisualStudio.com/DefaultCollection <"Project Name">
