    Example
    Interpolate Camera
    public Task<List<Camera>> GetInterpolatedCameras()
    {

    Interpolate Time

      });
    }
    Interpolate Range
    public Task<List<ArcGIS.Desktop.Mapping.Range>> GetInterpolatedMapRanges()
    {
      //Return the collection representing the map time for each frame in animation.
      return QueuedTask.Run(() =>

          return null;
    
        var animation = mapView.Map.Animation;
    
        var ranges = new List<ArcGIS.Desktop.Mapping.Range>();
        //We will use ticks here rather than milliseconds to get the highest precision possible.
        var ticksPerFrame = Convert.ToInt64(animation.Duration.Ticks / (animation.NumberOfFrames - 1));
        for (int i = 0; i < animation.NumberOfFrames; i++)
        {
          var time = TimeSpan.FromTicks(i * ticksPerFrame);
          //Because of rounding for ticks the last calculated time may be greeting than the duration.
          if (time > animation.Duration)
            time = animation.Duration;

        }
        return ranges;
