New Post: Merge AvalonDock and Themes together problem

Hi,
I'm trying to merge AvalonDock and 3 Themes projects to same project (ex: Lib.Avalon), in order to use AvalonDock in my main project. But, when I create an LayoutAnchorable and AutoHide is true. But the content of this layout was nothing, I also didn't see any header title and others command (AutoHide tooglebutton, menu, close button,...).
I had tried to change ThemeInfo to SourceAssembly but not work.
Any advice?

Thanks,
