My current project creates UI by WPF at runtime. Everything works well. The only issue about it is that the global WPF template is ignored for some reason. We created a skin that is attached to the main form and thus used by all xaml created UI elements. My own code just dynamically creates items like this: var textBox = new TextBox()...
