The document discusses the Universal App Platform in Windows 10, which allows developers to build a single app that can run on multiple device families from Windows PCs to Xbox to phones. With Universal Windows Platform apps, developers can use a single project and binary to target all Windows 10 devices, and the apps have access to common APIs and UI controls while supporting responsive and adaptive layouts. The platform provides a way for developers currently using XAML and C# with Windows 8.1 to start preparing their apps for the Universal Windows Platform.
