/// 1. If disposing is true, the method has been called directly

/// Both managed and unmanaged resources can be disposed.
///
/// 2. If disposing is false, the method has been called by the
/// runtime from inside the finalizer and you should not reference (access)
/// other managed objects, as they already have been garbage collected.
/// Only unmanaged resources can be disposed.
/// </summary>
/// <param name="disposing"></param>
/// <remarks>
/// 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,
/// it needs to be handled by fixing the bug.
///
/// If subclasses override this method, they should call the base implementation.
