/// 2. If disposing is false, the method has been called by the

/// If any exceptions are thrown, that is fine.
/// If the method is being done in a finalizer, it will be ignored.
/// If it is thrown by client code calling Dispose,

/// If subclasses override this method, they should call the base implementation.
