FileOpenPicker does not work in Page

Describe the bug

When you try to open FileOpenPicker in a page, nothing works. Nothing can be opened or the application simply closes. But on a window page it does work.

Steps to reproduce the bug

1. i create a page

2. i insert the following code: `` try { FileOpenPicker folderPicker = new(); folderPicker.ViewMode = PickerViewMode.List; folderPicker.SuggestedStartLocation = PickerLocationId.Desktop; folderPicker.FileTypeFilter.Add(“.jpg”); folderPicker.FileTypeFilter.Add(“.jpeg”); folderPicker.FileTypeFilter.Add(“.png”);

            var hwd = WindowNative.GetWindowHandle(this);
            WinRT.Interop.InitializeWithWindow.Initialize(folderPicker, hwd);
            var file = await folderPicker.PickSingleFileAsync();
   

   } catch (Exception ex) { ``

3. nothing happens during testing

Window is documented to implement IWindowNative (which WindowNative uses). In fact, IWindowNative documents that only Window implements the interface. What this basically means is that IWindowNative::get_WindowHandle/WindowNative.GetWindowHandle can only be used from something that derives from Microsoft.UI.Xaml.Window. So you will have to add some means for your page to obtain the main window. You can use your App class for this.
