Remarks
One key thing for this class is that, communications between main thread and worker thread are always accomplished with Dispatcher.BeginInvoke instead of Dispatcher.Invoke because sometimes these threads can run into deadlock situations as latter call wouldn't return unless Dispatcher processes it. For example first arrange pass of the main thread UI would cause the worker thread UI to arrange itself as we delegate that to worker thread but then worker thread UI needs to access the data model properties which is handled by the across thread COM calls via window messages.
