The best approach to showing / hiding windows individually

I am a student and am creating a WPF application in C #. It has three windows:

  • Enter the window

  • Create Account Window

  • and the main application window.

I uploaded a shape to show the type of navigation I'm trying to implement:

http://picturepush.com/public/8870554

I don’t think it’s correct for the window to show / hide inside the close / load event of another window.

  • Can someone show me the correct way to implement this navigation?

  • Also, is it okay to make three private properties of an application class window?

  • The last window has a frame control to support page navigation. Again, is it better to make the three pages private properties of the MainWindow application?

I'm sorry if this is so obvious or easy to do. Thanks
