I downloaded the WP7 Design Templates 1444 and opened the solution.  There is an unsatisfied reference to Microsoft.Phone.Controls.Toolkit.  Also the "toolkit:" alias definition was missing in file context_menu.xaml.  I have the RTM WP7 Dev tools installed but I don't find the Toolkit namespace.

Thanks for the Design Templates!

Hi Tom,
You will need to download and install the Silverlight for Windows Phone Toolkit: http://silverlight.codeplex.com/releases/view/52297

Cheers,
Kirupa (MSFT) =)

Thanks, Kirupa!

Thanks Kirupa. I've added the link to the Documentation section.

Thanks, Blender.

By the way, you might want to remove the source control bindings from the published project.  When I open it Visual Studio prompts me for a TFS login at CodePlex.

Also, I had to remove the page context_menu.xaml to get the solution to build.  When the page is included I get these errors:

The property 'Content' does not exist on the type 'ContextMenu' in the XML namespace 'clr-namespace:WindowsPhone7UXGuide'.

and	

Property 'ContextMenu' does not support values of type 'ContextMenu'.	

The related xaml:

<ListBoxItem ContentTemplate="{StaticResource DoubleLineListTemplate}" HorizontalContentAlignment="Left" Margin="0,0,0,4">
	<toolkit:ContextMenuService.ContextMenu>
		<local:ContextMenu>
			<toolkit:MenuItem Header="Item 1"/>
			<toolkit:MenuItem Header="Item 2"/>
			<toolkit:MenuItem Header="Item 3"/>
			<toolkit:MenuItem Header="Item 4"/>
			<toolkit:MenuItem Header="Item 5"/>
		</local:ContextMenu>
	</toolkit:ContextMenuService.ContextMenu>
	<local:MultiLineItem Line1="Largest (5 items)" Line2="Press and hold to view"/>
</ListBoxItem>
