Deleting a service model deletes only the elements displayed in the Explorer pane. It does not delete the classes, behavior models, property pages, or properties linked within the service model.
To delete a service model:
In the Explorer pane, expand Services > Service Models, then navigate to the service model element that should be deleted.
Right-click the element, then select Remove to open a confirmation dialog box.
Multiple elements could be selected for removal.
Click Yes to delete the service model.
The service model is removed from the Services hierarchy.
