How to make pushpin draggable over the map in bingmap wpf

Question

I am working on bingmap wpf. I have created pushpins on click event of mouse. Now I need to make it draggable and track the coordinate as per the pushpin location. Anybody has any idea on how to make the pushpin draggable and in which function we need to write code to update when it is released.

Thank you very much in advance

Vector _mouseToMarker;
private bool _dragPin;
public Pushpin SelectedPushpin { get; set; }

void pin_MouseDown(object sender, MouseButtonEventArgs e)
{
  e.Handled = true;
  SelectedPushpin = sender as Pushpin;
  _dragPin = true;
  _mouseToMarker = Point.Subtract(
    map.LocationToViewportPoint(SelectedPushpin.Location), 
    e.GetPosition(map));
}

private void map_MouseMove(object sender, MouseEventArgs e)
{
  if (e.LeftButton == MouseButtonState.Pressed)
  {
    if (_dragPin && SelectedPushpin != null)
    {
      SelectedPushpin.Location = map.ViewportPointToLocation(
        Point.Add(e.GetPosition(map), _mouseToMarker));
      e.Handled = true;
    }
  }
}
