datatemplate

In my MainWindow.xaml, I have the following reference to a ResourceDictionary:

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="MainSkin.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

In MainSkin.xaml, I define a datatemplate:

<DataTemplate x:Key="TagTemplate">
   ...
</DataTemplate>

Deeper within my application, I attempt to use this data template:

<ContentControl DataContext="{Binding Tag}" ContentTemplate="{StaticResource TagTemplate}"/>

The code compiles successfully, but when I attempt to load a Page or UserControl that contains this StaticResource, I get an exception saying that the TagTemplate can't be found.

What am I doing wrong?
