Universal Windows Platform (UWP)
UWP provides a common type system, APIs, and application model for all devices running on Windows 10. So, UWP enables development of universal apps for PC, tablet, Xbox, Surface Hub, HoloLens, or Internet of Things (IoT) devices.
UWP app developers get access to the Microsoft store that charges only 15 percent for non-gaming subscription-based apps, unlike Google Play Store and App Store. Other services include an execution environment (AppContainer) and Extension SDKs to call specialized APIs for different devices.
