Delete Attribute

The Delete Attribute command removes the selected attribute from the class (and all of its subclasses). When removing the attribute from the class, you will also strip it from all corresponding entities in the database. Once the database migration has completed, this action cannot be undone. If an attribute has been deleted and prior to database migration, you can use the Cancel Schema Editing command to discard all the schema edits and revert to the previous schema version.

 

To remove an attribute, you must remove it from the class in which it is specified (as opposed to attempting to remove an inherited attribute from a subclass).
