WPF Is it possible to host a control from one thread in another?

Question

I have a WPF app which has main window started in 'default' UI thread. I also have several other windows each has its own UI thread (by calling System.Windows.Threading.Dispatcher.Run() )

However for a specific reason I would like to have these windows as user controls hosted in the main window.

Is it possible (to have a control which was created in one thread to be hosted in a window created in another thread) ?

Answer 1

Pretty sure the answer is no based on one of the arguments for not using DependencyObject as the base of your ViewModels being threading issues.

And I quote:

A DependencyObject has thread affinity - it can only be accessed on the thread on which it was created.
