In my previous column, "Converting Windows Phone to Windows 8" I created a simple Windows Phone application that consumed an XML feed from Flickr and displayed a list of images. Then I showed you how to port that application, with a relatively high level of reuse, to Windows 8. This time, I'll look at extending the Windows Phone application to multiple pages, and focus on code compatibility and the navigation model. As a disclaimer, this is a discussion of code reuse rather than a demonstration of good UI design.
