[Syntax rule] Override of a base method cannot be less accessible than the base method It was possible to have a base method be decorated with protected and yet have an override of that method be private. Now when a base method is protected, the override method must be either protected or public, and the override method cannot be private. For more information, see Method Access Control. [Area]
