Documentation around ComponentDispatcher

[qmatteoq]

Hello, I'm working with a customer who is using WPF + Win32 interoperability to gradually modernize the UI of their application, by hosting WPF controls in a Win32 application.
As part of the project, they have setup a quite complex Win32 message loop, and as such, they are using the ComponentDispatcher class to share it with WPF. The class exposes the PushModal and PopModal member functions, however, it isn't really clear when you should use them. The official documentation is very generic, and I can't find good examples or explanations in Internet.

Is there any better pointer?

Thanks!
