Learn how to create an app with versions for the Windows Store, Windows Phone, and other platforms, using the new Portable Class Libraries support in Visual Studio 2012 to share code between the different versions of the app. We will see how the Model-View-ViewModel pattern (MVVM) is ideally suited to sharing code between platforms since it encourages a clean separation between the app logic, which can be shared, and the UI, which is platform-specific. We’ll see how to access non-portable functionality from portable code by creating a portable abstraction with platform-specific implementations. We will see several real-world demo apps, and touch on more advanced concepts such as navigation, inversion of control, and synchronizing data across multiple clients with Windows Azure Service Bus. To maximize your benefit from this session, having some prior experience with XAML-based apps and the MVVM pattern is recommended.
