Can you reference a XAML Resource from an External Assembly?

I have an assemblt called ControlsEx. In its project is a XAML file
that has some resources in a dictionary. How can I add those resources
into an Application Resource Collection. How do you reference it in the
Source property?

<Application.Resources>
<ResourceDictionary Source="r.xaml"></ResourceDictionary>
</Application.Resources>


Thanks.

Try this one. The source format is based on XPS, and the triple commas are
being used as escape codes.
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary
Source="pack://application:,,,/TheExternalResourceDll;component/TheFilePathInTheDll/MyExternalStyle.xaml"/>
</ResourceDictionary.MergedDictionaries>
<Style x:Key="YouCanStillDefineLocalResourcesHere">

</Style>
</ResourceDictionary>
</Application.Resources>

Keith,

Yes, that's exactly what I was looking for. You nailed it, thank you
