11. Per-Platform Registration from
Mobile Service
hub.wns.createNativeRegistration(
request.body.channelUri,
[request.user.userId, ‚sports‛],
function (error, registration) { ... }
);
hub.apns.createNativeRegistration(
request.body.deviceToken,
[request.user.userId, ‚sports‛],
function (error, registration) { ... }
);

12. Direct Registration from
Windows 8 Client
var channel = await PushNotificationChannelManager.
CreatePushNotificationChannelForApplicationAsync();
var hub = new NotificationHub(name, connString);
await hub.RegisterNativeAsync(channel.Uri);

13. Push from Mobile Service
hub.wns.sendToastText02(
[ ‘sports’, ‘news’ ],
{
text1: ‘Breaking news’,
text2: ‘AFC Ajax defeats FC Twente 3-0’
},

15. Push from Other .NET Backend
var hub = NotificationHubClient.
CreateClientFromConnectionString(connString, name);
var toast =
@‛...<text id=‘1’>‛
‚AFC Ajax defeats FC Twente 3-0‛
‚</text>...‛;
await hub.SendWindowsNativeNotificationAsync(toast);

Separate payload for each platform
But: More control over push customization

request.body.channelUri,
[ ‘sports’, request.user.userId ],
{ text1: ‘$(breakingnews)’ },
function (error, registration) { ... }
