In an earlier FAQ entry, I talked about how you can show a previously closed Windows Forms form. Well the same holds true for a WPF window and for the same underlying reason. When you close a WPF window, the native window is closed and destroyed. So trying to re-show it will just throw an exception. The solution is to either hide/show windows as required, or to instantiate and show a new window whenever that’s needed.
