telerik:Gauge not found

[Harry]

Hi all
I have been going though the RadControls for Silverlight and was working with the gauge control.  in the documentation it told you to use

<telerik:RadGauge>
             <StackPanel Background="{StaticResource BackgroundBrush}"
                HorizontalAlignment="Stretch">
                <StackPanel x:Name="spScales"
                Orientation="Horizontal"
                HorizontalAlignment="Center"
                Margin="10" />
            </StackPanel>
</ telerik:RadGauge>


And the gauge is not found.  I did check to make sure the gauge dll is loaded and when I use <control:RadGauge> loads fine.  Has anyone seen this issue and do you have any insight?
