Connected apps and devices (Project Rome)

This section explains how to connect apps across devices and platforms using Project Rome. Learn how to discover remote devices, launch an app on a remote device, and communicate with an app service on a remote device.

Most users have multiple devices and often begin an activity on one device and finish it on another. To accommodate this, apps need to span devices and platforms.

The Remote Systems APIs introduced in Windows 10, version 1607 enable you to write apps that allow users to start a task on one device and finish it on another. The task remains the central focus, and users can do their work on the device that is most convenient. For example, a user might be listening to the radio on their phone in the car, but when they get home they may want to transfer playback to their Xbox One which is hooked up to the home stereo system.

You can also use Project Rome for companion devices or remote control scenarios. Use the app service messaging APIs to create an app channel between two devices to send and receive custom messages. For example, you can write an app for your phone that controls playback on your TV, or a companion app that provides information about the characters on a TV show you are watching through another app.

Devices can be connected proximally through Bluetooth and wireless, or remotely through the cloud; they are linked by the Microsoft account (MSA) of the person using them.

See the Remote Systems UWP sample for examples of how to discover remote system, launch an app on a remote system, and use app services to send messages between apps running on two systems.
