You can use the AppDeleteRecursive method of the IIsWebVirtualDir object to delete Web application definitions from a metabase key and all subordinate keys. If the applications are running, they will be shut down. All resources associated with the applications, such as out-of-process packages, will be released. This action cannot be undone.
