Flag (default: false) which directs the built-in validation logic to throw an ArgumentOutOfRangeException exception when a field which is non-nullable is set to null / nothing. When false, the set action is silently ignored if a non-nullable field is set to null and results in a no-op, which is the behavior of v4.2 and earlier. When true, the set action results in the ArgumentOutOfRangeException.
