    public Task<bool> PreviousCameraAsync( 
       Nullable<TimeSpan> duration
    )
    Public Function PreviousCameraAsync( _
       Optional ByVal duration As Nullable(Of TimeSpan) _

    Parameters

    duration
    The amount of time to navigate the view to the new camera position. If null it uses the default navigation duration.

    Example
    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);
    }
    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
