The Windows 8 Metro platform redefines the way apps access and manipulate data. In this course we learn how to work with application data, that is, working data that is created and accessed by your app on a continuous basis. Traditionally, app data has been local, but Metro blurs the distinction between local and remote data by making things such as cloud storage and app-to-app integration an integral part of both the user and developer experiences. This course looks at accessing files, local and remote, as a content source for our apps; it explores app data storage and roaming as well as the settings contract; and it takes an in-depth look at app-to-app sharing through the sharing contract. Before doing so, however, it starts with a fresh look at the UI side of things, including Metro controls and data binding. After watching this course, you should feel comfortable accessing, listing, updating, roaming and sharing data in your metro apps.
