- Nowadays WP7 devices will not be able to upgrade to the new operating system. That is a huge inconvenience. If we want to develop an app for all Windows Phone devices, don’t use WP8 or make one app for WP7 and another for WP8.
- All Windows OS will be more similar. Obviously this is a big advantage, it will be much easier to port code between PC, mobile or tablet applications.
By the way, don’t worry about your WP7 apps, they will run in WP8, as Larry Lieberman stressed.
That said, we want to share with you some basic functionalities we have been using in our first steps with WP7. One of ARLab common practices in app development is to include within a parent class the recurring functions used in all screens.
First we will share how iOS & Android achieve our goal. Then, we will give a step-by-step explanation of how WP7 reaches the same point, if possible. It’s pretty simple, and quite useful for code maintaining.
