Summary0002522: Dispatcher.BeginInvoke never invokes the callback
DescriptionI have a class that inherits from DispatcherObject. The class contains methods to call BeginInvoke on the Dispatcher but the callbacks never get called unless I use Application.Current.Dispatcher. The following link contains code to reproduce the problem.

Hi, I found that creating classes directly inheriting from DispatcherObject won't provide the correct Dispatcher, this is a bug.
If you change your base class to DependencyObject in your sample then it will correctly invoke the callback.

I undertand. Changing to DependencyObject works but that won't help for our production scenario, we have a class that needs to derive from DispatcherObject. Is this a bug that will be fixed in the next version?
Thank you.

Yes, of course, this is a bug that we will solve for the next version.
