What is a "Page Function"?

Question

What is a "Page Function" in WPF and what have you used it for? Also, it this something you think Silverlight would benefit from?

Answer 1

PageFunction is a cross between a Page and a Function (method). So basically, you can navigate to it like a page, but it can also return a value like a method. This is useful for when you want to show the user a page and receive feedback in the calling page. You could use a popup box of sorts, but in some patterns and situations, a page is preferable.

There's a good explanation of PageFunctions in this article.
