It means thisusing Windows.Media.Capture;

var ui = new CameraCaptureUI();ui.PhotoSettings.CroppedAspectRatio = new Size(4, 3);

var file = await ui.CaptureFileAsync(CameraCaptureUIMode.Photo);

if (file != null) { var bitmap = new BitmapImage() ; bitmap.SetSource(await file.OpenAsync(FileAccessMode.Read)); Photo.Source = bitmap;}

It’s dangerous to go alone! Take this.
