Hello again -
Team Foundation Server (TFS) is designed not to permanently delete items you remove. Such as projects, branches, or even unused folders. It is a version control system for source code afterall. Though there is a way around this via command line if you are absolutely sure you want to remove those items.
I use a project here as an example. But you can really target anything. Simply by adjusting the path (URL) to the item. To delete a project completely from Team Foundation Server you will need to run
the following command within your Administrator Visual Studio Command Prompt
[/force] [/excludewss] /collection:<url> <team project
[/q] - Do not
prompt for confirmation.
[/force] - Continue even if some data cannot be deleted.
[/excludewss] - Exclude the project's SharePoint® portal site when deleting the
project. This option will leave site intact so that it remains for other
projects that may be using it.
/collection:<url> - The url for a Team Project Collection.
<team project name> - The name of the project. Use quotes if there are
spaces in the name.
