Just out of curiousity why would need to get the handle? What is it that you are trying to do?

No, not in the sense of window handle you obtain from the WindowInteropHelper. They are not Windows windows. The technology is based on DirectX and provides alternative windowing mechanism inside the WPF window. In a way, the technology is a good attempt to go away from Windows as OS, as most of its implementation is not related to Windows API. And in practice, you never need any window handles.

In principle, you can use any valid windows handle to add or find (if any) child windows, work with them, etc. All you need is pure (unmanaged) Windows API, P/Invoked or obtained using mixed-mode projects using C++/CLI. I would advise to resist this temptation by all means. Should I even explain why it's very bad? WPF is self-contained (except the top-level window) and provides you with everything you need.
