Return an object from a popup window

Question

I have a Window which pop-ups another Window. I want the second Window to be able to return an object to the first Window when a button is pressed. How would I do this?

I know this is an old one, but I was looking for the same information for a WPF application I'm working on. I found this site to be really helpful:

This is written for Windows Forms, but if you ignore the part about passing values to the new window, it still worked and had some really good information.

On a side note, to pass values to the new window, this was really helpful:
