Cannot reuse a deleted Managed Service Application name in SharePoint 2010

If you arrive in a situation where you cannot reuse an old deleted service application name because its supposedly in use or similar, then you can run the following commands.

The first one is as follows - in powershell;

C:\Users\installation> get-SpServiceApplicationPool

This will now show up the names for the Application Pools. Simply identify which one you need to delete, and then run the below command and adjust with the relevant name;

C:\Users\installation> Remove-SpServiceApplicationPool "APPLICATION NAME HERE"
