essentially allows you to treat a page navigation like a function call, in which a page navigates to (calls) a page function.
To enable function call semantics, provides the following capabilities:
When the page function has finished processing, the page function code calls OnReturn to return to the calling page.
To detect when a page function has returned, the calling page can handle the Return event.
To return a value, the page function creates an instance of the ReturnEventArgs<T> class and sets the Result property with the return value. The calling page can retrieve this value from the ReturnEventArgs<T> object that is passed to the Return event handler.
By default, a is retained in navigation history after it returns. To ensure that it is not retained in navigation history, its RemoveFromJournal property should be set to true.

See Navigation Topologies Overview for information on complex navigation structures that benefit from page functions.
