WPF System.Windows.Navigation.NavigationWindow in MFC application

Question

I need to use a WPF Lib with a System.Windows.Navigation.NavigationWindow in a MFC Win32 app but I have a black screen instead of my WPF Windows. I have no error message in the debug output.

All the other WPF control I tried work fine in MFC (button, grid, D3D with C++).

Anyone have an idea how to debug that or how to investigate that?

Thanks

EDIT: The problem happen with System.Windows::Window too. And it work fineif I use my WPF in a WPF App.

I can't find a working solution but here's my workaround at the moment.

I created a separate a WPF app with my WPF Lib.

And in my MFC app I do:

HWND wpfProcessMainWnd = CreateProcessWPF();

SetParent(wpfProcessMainWnd, hWnd);

DWORD style = GetWindowLong(wpfProcessMainWnd, GWL_STYLE);
style |= WS_CHILD;
style &= ~(WS_BORDER | WS_OVERLAPPEDWINDOW);

SetWindowLong(wpfProcessMainWnd, GWL_STYLE, style);

SetWindowPos(wpfProcessMainWnd, NULL, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOZORDER);
