Nowadays, an app's capability to work online and offline is essential to users. This course, Occasionally Connected Windows Mobile Apps: Consumer, will teach you how to design an app that caches data while offline and keeps track of the consumer's actions. You'll also learn how to send that data to the server without user intervention when they reconnect. You'll discover how to give the server the agency to act on the user's behalf, as well as use that data to provide a continuous experience across devices. Finally, you'll be able to put all of these patterns into practice in a Universal Windows App that will get 5-star reviews. By the end of this course, you'll be able to design great apps that operate perfectly whether they're online or not.
