Display a WPF window inside another

Question

Before pointing me to http://stackoverflow.com/questions/1287820/have-a-wpf-window-inside-another-wpf-window or telling me that MDI is soooo 1995, let me explain my application.

I'm creating a MessageBanner window that works similar to the message banner we see in several sites nowadays (including SO)

I want client code to call my message banner using four different modes:

MessageBanner.Show(content);
MessageBanner.Show(content, ownerWindow);
MessageBanner.ShowModal(content);
MessageBanner.ShowModal(content, ownerWindow);

I believe you got the application.

The thing is that when ownerWindow is displayed, I want to display my MessageBanner window inside the ownerWindow.

Any ideas on how to do it?

I'm not sure why you want to add it as a Window. It sounds to me like you'd want to create it as an adorner rather than a window.
