We can change the dispatcher in dependency property recursively.

Sometime, we may write the code cross thread to improve performance. But we are hard to share the dependency property to other thread.

As we know the DependencyObject is inherited from DispatcherObject in WPF. And the WPF use DispatcherObject.CheckAccess to check the calling thread and the creating thread. Some of the dependency property will call the DispatcherObject.DetachFromDispatcher to set their dispatcher to null to share the dependency property to other threads.

But I need to change all of the DependencyObject in a control that I want to share it with other threads. I hope we can use some method like Freeze to freeze some control to share it with other threads. Or we can set the dispatcher in dependency property recursively.
