InfoBox MapControl WPF (not Silverlight)

Is it possible to show a floating "infobox" when you press a push pin using "Bing Maps Windows Presentation Foundation (WPF) Control, Version 1.0"?

I can create push pins and I can detect when they are clicked, but I don’t have any idea how to show a floating window. It sounds like I can use a InfoBox, but I don't have this...is this only available in Silverlight?

It is using Visual Studio 2010 for a WPF application.

You can use Canvas & Thumb:

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:maps="clr-namespace:Microsoft.Maps.MapControl.WPF;assembly=Microsoft.Maps.MapControl.WPF" 
        x:Class="WpfApplication15.MainWindow">
    <Grid>
        <maps:Map/>
        <Canvas>
            <Grid Name="grid"
                  Canvas.Left="0" Canvas.Top="0"
                  Width="200" Height="100">
                <!-- Your control begin -->
                <Rectangle Fill="Blue"/>
                <!-- Your control end -->
                <Thumb Name="thumbMove">
                    <Thumb.Template>
                        <ControlTemplate>
                            <Rectangle Fill="Transparent"/>
                        </ControlTemplate>
                    </Thumb.Template>
                </Thumb>
            </Grid>
        </Canvas>
    </Grid>
</Window>

thumbMove.DragDelta += (s, e) =>
{
    Canvas.SetLeft(grid, Canvas.GetLeft(grid) + e.HorizontalChange);
    Canvas.SetTop(grid, Canvas.GetTop(grid) + e.VerticalChange);
};
