This can occur if you have a reference to the Web application somewhere else in the system (e.g. the Web application is a component of another distributed application). A similar error condition can occur when you have added a monitor targeting the Web application and try to delete the Web application without removing the monitor first.

You need to first remove the reference or just remove the object which references the Web application (e.g. the distributed application in the sample above). Then you will be able to delete the Web application.
