WPF User control library - form doesn't show up

I need to create .dll which utilizes WPF forms. I want to wrap this Custom.dll into COM object and then use via VBA-like script language. After some research, I've decided to use WPF User Control Library, as the best approach. But I've ran into two problems:

1. For testing needs, I'm referencing and debugging my Custom.dll in ConsoleApplication project. But I also have to reference PresentationFramework, PresentationCore and WindowsBase libraries as well. This is inappropriate for my task, because later, I can't reference them in the VBA-like script (I have access only to COM objects via CreateObject()). It looks pretty weird to me, because all libraries are already referenced inside Custom.dll, why I have to do it again? It's not typical for .dll, isn't it?


2. Even when I'm referencing these libraries, and trying to create instance of my Custom.UserControl1 nothing appears on screen: no runtime errors happen, everything looks just fine, InitializeComponent function run perfectly, but after that - nothing shows up.

I've tried to create another similar project, thinking it might be some random-half-magic stuff, but it didn't help too.
