Vista - Display clipboard image?

I'm totally new to WPF, and I'm having trouble displaying an image from the
clipboard. I can verify that there is an image there, and from the resulting
BitmapSource I get from Clipboard.GetImage(), I can verify the the image
width and height are correct, but it doesn't actually show up when I run the
application. Just a blank screen. Is there something else I'm missing here?
Here's the code for my window, distilled down to the relevant parts:

using System.Windows;
using System.Windows.Controls;
using System.Windows.Media.Imaging;

namespace Project1
{
class Window1 : Window
{
public Window1()
{
this.Title = "Clipboard image";
if (Clipboard.ContainsImage())
{
BitmapSource bs = Clipboard.GetImage();
Image i = new System.Windows.Controls.Image();
i.Source = bs;
this.AddChild(i);
}
else
this.AddChild("No Content in clipboard");
}
}
}

Any suggestions would be much appreciated.
