    Go To Previous Camera
    public Task<bool> ZoomToPreviousCameraAsync()
    {
      //Get the active map view.
      var mapView = MapView.Active;
      if (mapView == null)
        return Task.FromResult(false);
    
      //Zoom to the selected layers in the TOC
      if (mapView.HasPreviousCamera())
        return mapView.PreviousCameraAsync();
    
      return Task.FromResult(false);
