At Mobile World Congress 2015, Kevin Gallo gave the world a first look at the Windows 10 universal app platform. Kevin provided background into how developers can achieve scale through reach across device types, and introduced adaptive UX, natural user inputs and cloud-based services to help developers deliver unique and personal experiences with Windows 10. Finally, Kevin showed how developers can package existing websites, which (once published to the store) can call universal APIs to create an engaging user experience. The video incudes demos of apps running across the Windows universal app platform on PC, phone, and Xbox One.
