WPF Find window instance

Question

I have created an instance of a window inside a class, but I am unable to access the instance of the window from my other class directly.

Is there a way to reference

Answer 1

Application.Current.Windows gives you all windows, shouldn't be hard to find using its type.

(As Ed pointed out this does not sound like very good design, so you might want to think about how you can get things done without messy window references)
