Minimum Code for Silverlight Rotation Animation

This is the minimum code for animate rotating a Silverlight element (a variable named Element):

   Element.RenderTransformOrigin = new Point(0.5, 0.5);
   Element.RenderTransform = new RotateTransform();
   DoubleAnimation da = new DoubleAnimation
   {
     From = 0,
     To = 360,
     Duration = TimeSpan.FromSeconds(0.5)
   };
   Storyboard.SetTarget(da, Element.RenderTransform);
   Storyboard.SetTargetProperty(da, new PropertyPath(RotateTransform.AngleProperty));
   Storyboard sb = new Storyboard();
   sb.Children.Add(da);
   sb.Begin();
