In your App class you have to override the CreateXamlProvider to return a xaml provider that can load resources from all your assemblies. By default we provide the EmbeddedXamlProvider class that can chain several providers, for example you can do something like this:
partial class App : Application
{
  ...
  protected override XamlProvider CreateXamlProvider()
  {
    XamlProvider buttonsProvider = new EmbeddedXamlProvider(Assembly.Load("Buttons"), "Buttons");
    
    Type type = this.GetType();
    return new EmbeddedXamlProvider(type.Assembly, type.Namespace, buttonsProvider);
  }
}

Hi,

The libraries included in the ManagedSDK are xamarin applications and cannot be loaded that way.
The external library should be defined as a Class Library (.netstandard 2.0) and depend on Noesis.GUI for defining your user controls.

Could you tried that?

Is the class library referenced in the application?
Expand the application project in Visual Studio, right-click on References and select "Add Reference...", then select the class library project.
Otherwise the library won't be included in the android package when building and deploying.
