Contracts and Pickers: Building Apps that Work Together on Windows

With Windows Phone 8.1 we're bringing many of the Windows APIs that allow apps to talk to each other to the Phone! Your apps now have the ability to share photos, text, links and pretty much anything you want to built-in apps like Mail or Messaging and social networks like Facebook or Twitter. You can also open and save files to the SD card, Phone storage and OneDrive or other cloud storage services. These are just some of the things enabled by the new contracts in Windows Phone 8.1. Arun and John will dive into each of these contracts with demos on how to use them in your Windows Phone 8.1 apps as well as your existing Silverlight apps.
