How can I access resources from external assembly?

Question

I don't seem to be able to access remote resources from an external assembly.

The following line in MainWindow.xaml isn't working, no background color is getting displayed:

 <StackPanel Grid.Row="0" Background="{DynamicResource {ComponentResourceKey TypeInTargetAssembly={x:Type res:DummyForSharingResources}, ResourceId=TestBg}}"></StackPanel>  

I published a corresponding repository to GitHub containing my Visual Studio 2019 solution. It contains all the details.

What I did so far

• "Themes/generic.xaml" file created in supplemental assembly (StylesAndResources), filled with resources.
• ThemeInfoAttribute updated in application assembly to reference ResourceDictionaryLocation.ExternalAssembly.
• Dummy class created in StylesAndResources in order to be able to have a ComponentResourceKey be generated.

What am I doing wrong?

Please add AssemblyInfo.cs to your project StylesAndResources:

using System.Windows;  
  
[assembly: ThemeInfo(  
    ResourceDictionaryLocation.None, //where theme specific resource dictionaries are located  
                                     //(used if a resource is not found in the page,  
                                     // or application resource dictionaries)  
    ResourceDictionaryLocation.SourceAssembly //where the generic resource dictionary is located  
                                              //(used if a resource is not found in the page,  
                                              // app, or any theme specific resource dictionaries)  
)]
