In this session you will learn how to build a Metro style device app that is automatically installed with the camera. This session will also cover how developers can use Windows APIs to bring branded video and photo capabilities to their own Metro style apps.

Windows 8 introduces a new print experience for apps that implement the new print contract. This experience can be extended to your printer with a Metro style app that is automatically installed with the device. In this session, you will learn how to develop an app that can access printer status, customize the print experience with differentiated device capabilities and report printer status through notifications.

Windows offers a wide variety of input mechanisms for players to control your Metro style game, from touch, to gamepads, to classics like the keyboard and mouse, or even device sensors such as an accelerometer. At first glance, it may seem challenging to handle it all, but the input and sensor APIs in Windows are easy to learn and quick to master. Learn in this session how to develop entertainment apps that are easy to control on any hardware form factor.

We live in a connected world. Whether it's a spouse away on a business trip, a daughter away at college, or our parents in New York, we love to stay connected with each other.

Learn how to leverage the new media capture APIs, take advantage of the new Bluetooth features and unleash cool media tricks that will add polish to your app and delight your customers.

Do you have existing Windows apps? We'll show you the "compatible by design" principles and features of Windows 8 for future-ready desktop apps. Through this session, you will discover how to make your desktop apps work harmoniously alongside Metro style apps and how to position your app for the future by applying new Metro style design principles.

The canvas paint sample is a Metro style app using HTML optimized for painting on a touch surface and taking advantage of local storage. Come and see the author of this app take you through it, explaining what he's learned, to help you get started building your own Metro style apps using HTML.

Windows 8 exposes a broad range of audio and video functionality for Metro style apps, and extensibility in the media platform provides advanced apps the option to do more. Apps can use the power and efficiency of native code media extensions to deliver additional effects, arbitrary processing, media formats and media delivery support. Learn how to develop, deploy and leverage these plug-ins for advanced playback, capture, sharing and transcoding.

Learn how to build Metro style apps for customers in any market or language. Get an overview of the easy steps required to make a world-ready app, and learn how to use localization and formatting APIs with familiar HTML5 and XAML programming concepts.
