Navigation: Page or Window?

Question

.NET

What is the best way to implement navigation in a WPF application - through windows or pages?
If pages, is it possible to transfer data between them?
What are the benefits of page navigation?
PS I'm making a single-window (in the sense only one window is open at the same time) application.

Answer 1

Navigation is better done paginated.
Data transfer is always possible. But to do it smartly and know the benefits, learn MVVM.
