Assembly-wide / root-level styles in WPF class library

Question

I have a C# (2008/.NET 3.5) class library assembly that supports WPF (based on this article).
I\'ve created several windows, and am now attempting to create a common style

Dr. WPF (or the person formerly known as Dr. WPF) has a great post on the subject.

Here's an excerpt from the post where they create the Application object and add resources:

if (Application.Current == null)
{
    // create the Application object
    new Application();

    // merge in your application resources
    Application.Current.Resources.MergedDictionaries.Add(
        Application.LoadComponent(
            new Uri("MyLibrary;component/Resources/MyResourceDictionary.xaml",
            UriKind.Relative)) as ResourceDictionary);
}

Since my assembly is hosted via interop I had to add setting the ShutdownMode as follows and shutdown when finished:

new Application() { ShutdownMode = ShutdownMode.OnExplicitShutdown };

It worked like a charm.
