Styling SL Toolkit Accordion with Jetpack Theme

I am trying to use the newly released Jetpack theme for a Silverlight 4 application. TabControl and buttons style nicely, but I cannot get the Accordion control to pick up the Jetpack style.

I have created a default 'Silverlight Navigation (JetPack Theme)' VS project and added the following definitions to the XAML file

xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"       
xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit" 

And then I've added the accordion control like this:

    <toolkit:Accordion Grid.Column="0"
                       SelectionMode="OneOrMore" ExpandDirection="Down" SelectionSequence="Simultaneous">
开发者_运维技巧        <toolkit:AccordionItem Header="Stages">
            <TextBlock>Stages</TextBlock>
        </toolkit:AccordionItem>
        <toolkit:AccordionItem Header="Products">
            <TextBlock>Products</TextBlock>
        </toolkit:AccordionItem>
    </toolkit:Accordion>

This control renders as part of the page, but using the default toolkit style, rather than the JetPack style like the other controls on the page. Am I using the wrong toolkit namespace? I've tried to modify ToolkitStyles.xaml to add a key to the accordion style and reference the style via Style attribute in toolkit:Accordion but without success.

Have anyone successfully styled the accordion control with the JetPack theme?

After following the instruction in App.xaml (uncomment the reference to Assets\ToolkitStyles.xaml and setting the build action on that same file) I got the sample project to compile and run successfully with the accordion control styled.
