RenderTransform Compilation Error

[Kevin Marois]

I have a SpinningIndicator in a USERCONTROL. It works fine with no problems. Now, I want to move it to a CUSTOMCONTROL. But it fails to compile on this line:

DoubleAnimation Storyboard.TargetProperty="RenderTransform.Angle"

The error message is

Cannot resolve all property references in the property path 'RenderTransform.Angle'. Verify that applicable objects support the properties.

Here's my XAML

    <Setter Property="Template">

        <Setter.Value>

            <ControlTemplate TargetType="{x:Type ctrl:SpinningIndicator}">

                <Border Background="{Binding Background, RelativeSource={RelativeSource TemplatedParent}}"
                        BorderBrush="{Binding BorderBrush, RelativeSource={RelativeSource TemplatedParent}}"
                        BorderThickness="{Binding BorderThickness, RelativeSource={RelativeSource TemplatedParent}}"
                        Margin="{Binding Margin, RelativeSource={RelativeSource TemplatedParent}}"
                        Padding="{Binding Padding, RelativeSource={RelativeSource TemplatedParent}}">

                    <Grid>

                        <Grid.RowDefinitions>
                            <RowDefinition Height="\*"/>
                        </Grid.RowDefinitions>

                        <Canvas Grid.Row="0" 
                                Name="Canvas1"  
                                RenderTransformOrigin="0.5,0.5"  
                                HorizontalAlignment="Center"         
                                VerticalAlignment="Center" 
                                Width="120" 
                                Height="120">

                            <Canvas.RenderTransform>
                                <RotateTransform Angle="0" />
                            </Canvas.RenderTransform>

                            <Canvas.Style>
                                <Style TargetType="Canvas">
                                    <Style.Triggers>
                                        <Trigger Property="IsVisible" Value="True">
                     </x-turndown>

Try changing the TargetProperty to just "Angle" instead of "RenderTransform.Angle" - no guarantees, but it might work.
