PeerFinder.Start() | start() method

Applies to Windows and Windows Phone

Makes an app discoverable to remote peers.

Syntax


public:
static void Start()

Parameters

This method has no parameters.

Remarks

You can call the Start method to begin the process of finding a peer app and to make your app discoverable to remote peers that call the FindAllPeersAsync method. A peer is a device that has an app running in the foreground with a matching AppId. A peer can also have a matching Browse Id that's specified as an alternate identity. For more information, see AlternateIdentities.

You can connect to only one peer at a time if your app is in the peer or client role. If your app is in the host role, you can connect up to 5 clients at a time.

When an app is activated by tapping a nearby device, the activation parameters indicate whether the PeerFinder should be started or if the app was launched with activation arguments. The format of the activation parameters is "Windows.Networking.Proximity.PeerFinder:StreamSocket Role=<Host|Client>". For more information, see the "Activating apps using Proximity" section of Supporting Proximity and Tapping.

Important  

Always set the DisplayName property to a unique value for your app before you call the Start method.
