Александр Краковецкий_Разработка универсальных приложений для Windows Phone 8.1 и Windows 8.1
The document discusses how developers can reuse code between Windows Store apps and Windows Phone apps. It explains that with Windows 8.1 and Windows Phone 8.1, there is over 90% API convergence between the two platforms using the shared Windows Runtime. This high degree of convergence means developers can write common logic, UI, and data code once and share it across devices. The document provides examples of platform-specific APIs and conditional compilation to support code sharing.
