Gtk theme in GTK# (Windows)

I'm trying to change the theme in GTK# (*OS: Windows, IDE: Xamarin*). But I get next issues: 1. I was able to find only one theme which correctly render, it is Orta. All was well, except for *lags and freezes*. Here is my code: string Resource_File = Orta\\gtk-2.0\\gtkrc
