If you find yourself in need to open a WPF Window from a WinForms program - this is one way to do it (works for me):
1) Create/Add a new project of type "WPF Custom Control Library"
2) Add a new Item of type "Window (WPF)"
3) Do your thing with the WPF Window
4) From your WinForms app, create and open the WPF Window:
using System; using System.Windows.Forms; using System.Windows.Forms.Integration;
var wpfwindow = new WPFWindow.Window1(); ElementHost.EnableModelessKeyboardInterop(wpfwindow); wpfwindow.Show();
There you go!
The EnableModelessKeyboardInterop() call is necessary to handle keyboard input in the WPF window if loaded from a non-WPF host like WinForms. I understand there are other ways to do this and you can read more about WPF/WinForms interop here.
