Development in Windows 8-use a unified principle diagram of convertible background (XAML) in applications

Scenario

The application uses a unified switchable background. When the background is switched, the background of all pages is switched at the same time. It seems like a simple task, but it still takes a little effort.

Ideas

The idea is simple: first create an observed backgrounduri class, which is mainly associated with several background image Uris, and then bind the same imagesource to all application pages, its URI is associated with the background object. Then, a backgroundmanager class is created to regularly change the URI attribute in the backgrounduri.

This idea may not be mature, but I did not expect a better method. This structure is relatively simple, and the following is a sketch.
