如何获得 WinUI 控件的父级 Window？

Question

I need to get a reference to the parent Microsoft.UI.Xaml.Window for a Control . Is there a way to do that in Project Reunion 0.5? Window.Current does not work in a desktop app.

On WinUI3 since the window is platform-dependent you access it differently. For Windows Desktop it uses Win32Inerop:

private AppWindow GetAppWindowForCurrentWindow()
        {
            IntPtr hWnd = WindowNative.GetWindowHandle(this);
            WindowId wndId = Win32Interop.GetWindowIdFromWindow(hWnd);
            return AppWindow.GetFromWindowId(wndId);
        }
