Table Per Type Inheritance Update Error
I am getting and error:
"message": "Error updating student: The instance of entity type 'AppUser' cannot be tracked because another instance with the key value '{Id: 59ade4e2-b505-4579-a797-bf6c57e6b8ef}' is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached."
please help me solve this problem. Methods and the entity are within the updateaMethod.txt
