I created a test application with a treeview using implicit themes with the XAML files loaded into project. That works fine. If I move the treeview into a usercontrol in a separate project, it does not work. I tried both methods from here with no success:

https://blogs.msdn.microsoft.com/wpfsdk/2007/06/08/defining-and-using-shared-resources-in-a-custom-control-library/

It fails when loading Telerik.Windows.Controls.Navigation.xaml. It doesn't have a problem loading Telerik.Windows.Controls.xaml. The sample in the link

As a side note, I am doing the same thing with the map control and don't have any issues with it.

Link to the Project:

Here's the snippet from the UserControl:

<UserControl.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Themes/System.Windows.xaml"/>
            <ResourceDictionary Source="Themes/Telerik.Windows.Controls.xaml"/>
            <ResourceDictionary Source="Themes/Telerik.Windows.Controls.Navigation.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</UserControl.Resources>

Hello Jason,

When you define control library that uses third party dlls (as Telerik) you will need to reference those dlls also in the project that uses the control library. In order to resolve the error on your side you can reference the Telerik dlls also in the TelerikWpfApp1.
