Examples

See the code example below for the process of joining a remote session (including obtaining a reference to a RemoteSystemSession instance).

public async void JoinExistingSession() {

    // request to join. sessionInfo has already been selected by user.
    RemoteSystemSessionJoinResult joinResult = await sessionInfo.JoinAsync();

    // process the result
    if (joinResult.Status == RemoteSystemSessionJoinStatus.Success) {

        // if the join was successful, acquire a reference to the session
        currentSession = joinResult.Session;

        // optionally handle the disconnected event
        currentSession.Disconnected += async (sender, args) => {
            // update the UI, using args.Reason
        };

        // update the UI with the session.DisplayName and 
        // session.ControllerDisplayName strings. Save a reference to 
        // this RemoteSystemSession, to use when the user selects
        // this session from the UI

    } else {
        // join request failed. optionally update UI
    }
}

Alternatively, see the following code for an example of how to create a remote session and handle join requests.

public async void StartNewSharedExperience() {

    var manager = new RemoteSystemSessionController("Bob’s Minecraft game");

    // register the following code to handle the JoinRequested event
    manager.JoinRequested += async (sender, args) => {
        // Get the deferral
        var deferral = args.GetDeferral();

        // display the participant (args.JoinRequest.Participant) on UI, giving the 
        // user an opportunity to respond
        // ...

        // If the user chooses "accept", accept this remote system as a participant
        args.JoinRequest.Accept();
    };

    // create and start the session
    RemoteSystemSessionCreationResult createResult = await manager.CreateSessionAsync();

    // handle the creation result
    if (createResult.Status == RemoteSystemSessionCreationStatus.Success) {
        // creation was successful
        RemoteSystemSession currentSession = createResult.Session;

        // optionally subscribe to the disconnection event
        currentSession.Disconnected += async (sender, args) => {
            // update the UI, using args.Reason
            // ...
        };

        // Use session ...

    } else if (createResult.Status == RemoteSystemSessionCreationStatus.SessionLimitsExceeded) {
        // creation failed. Optionally update UI to indicate that there are too many sessions in progress
    } else {
        // creation failed for an unknown reason. Optionally update UI
    }
}

Remarks

Remote System Sessions is a part of the broader Remote Systems feature set. It allows an app to establish a session object as an intermediate third party that two or more devices can continually communicate through, enabling a number of new cross-device scenarios such as remote app messaging.

A session that has been joined is represented by a RemoteSystemSession object. A session that is known about but has not been joined is represented by a RemoteSystemSessionInfo object.
