Answer 1

I managed to add CameraOverlayView, "to allow the user to take a picture inside the given rectangle"

private UIImagePickerController _imagePicker;

private void OpenCameraAndTakePhoto() { 
    _imagePicker = new UIImagePickerController();
    _imagePicker.SourceType = UIImagePickerControllerSourceType.Camera;
    _imagePicker.MediaTypes = UIImagePickerController.AvailableMediaTypes(UIImagePickerControllerSourceType.Camera);
    _imagePicker.FinishedPickingMedia += Handle_FinishedPickingMedia;
    _imagePicker.Canceled += Handle_Canceled;
    _imagePicker.ShowsCameraControls = true;
    UIView view = new UIView(new CGRect(30, 200, 250, 120));
    view.Layer.BorderColor = UIColor.Blue.CGColor;
    view.Layer.BorderWidth = 3.0f;
    _imagePicker.CameraOverlayView = view;

    PresentModalViewController(_imagePicker, true);
}
