Invalid Type on Transition Easing

[Dustin Clonch]

On the QuarticEase below, I am getting an "Invalid Type" Error. 
Any Easing function I try to enter gives me the same Invalid Type error. Help please!
Visual Studio 2010 w/ .Net 4 with RadControls for WPF 2011_1_0419.

<Grid x:Name="MainGrid" Background="{StaticResource HelpBrush}">

        <telerik:RadTransitionControl x:Name="TransControl" Width="484" Height="384" Duration="0:0:1"

                                      Padding="32">

            <telerik:RadTransitionControl.Transition>

                <telerik:PerspectiveRotationTransition Direction="Left">

                </telerik:PerspectiveRotationTransition>

            </telerik:RadTransitionControl.Transition>

            <telerik:RadTransitionControl.Easing>

                <QuarticEase EasingMode="EaseOut"/>

            </telerik:RadTransitionControl.Easing>

        </telerik:RadTransitionControl>
</Grid>

Hello Dustin,

I suppose you are using RadControls for WPF 3.5. If this is true, you cannot use Microsoft easing functions with RadTransitionControl. You could use them and run your sample code without any trouble together with RadControls for WPF 4.0.
However if you want to use RadControls for WPF 3.5, you will need to implement your own easing functions.

Hope this helps.

Best wishes,
