Windows Phone 8 uses Microsoft Push Notifications Windows 8/8.1 uses Windows Notification Service Windows Phone 8.1 uses Windows Notification Service

Lets call these the “.NET/MPN APIs” We’re here for you Microsoft.Phone.Notification, Microsoft.Phone.Shell HttpNotificationChannel, ShellTile, ShellTileSchedule, ShellToast There is some magic happening Platform is pure WNS with a.NET notification frosting OS upgrades The Shim

WNS sends notification to device WP8.0 APP.NET APIs WinRT APIs Notification Client Platform MPN NOTIFY WNS NOTIFY Send MPN Shim Push URI Platform requests MPN Shim channel from WNS MPN shim does all the authentication and translation logic to WNS. 1 WNS will create a channel using the MPN shim domain (both http & https) 2 3 PERSISTENT CONNECTION 4 5 App Cloud Service 6 WNS 7

No need to rewrite or change All.NET APIs are there – nothing is deprecated Behavioral improvements BindToShellTile and BindToShellToast always succeeds IsShellTileBound and IsShellToastBound always true BindToShellTile doesn’t need the URI list anymore, but doesn’t break if you give it Find  Returns Null  You call Open  ChannelUriUpdated -every launch and resume

No need to rewrite or change If you domain whitelist We are keeping the existing format Very likely to look like but don’t depend on ithttp://s.notify.live.net Don’t use URI length restrictions We used to return URIs around 130 characters Approximately 200 characters currently

Let’s call these the “WinRT APIs” All the familiar namespaces are here: Windows.UI.Notifications, Windows.UI.StartScreen, Windows.Networking.PushNotifications The code just works (Go ahead, try the notifications code behind the Windows samples, they’ll work – seriously!)

WP8.1 APP.NET APIs WinRT APIs Notification Client Platform Platform requests channel from WNS 1 Secure WNS channel for your application PERSISTENT CONNECTION WNS

WP8.1 APP.NET APIs WinRT APIs Notification Client Platform WNS Push URI Platform requests channel from WNS 1 2 PERSISTENT CONNECTION App Cloud Service WNS

WP8.1 APP.NET APIs WinRT APIs Notification Client Platform WNS Push URI Platform requests channel from WNS 1 2 PERSISTENT CONNECTION App Cloud Service WNS Request access token 3

MSDN:

WP8.1 APP.NET APIs WinRT APIs Notification Client Platform WNS Push URI Platform requests channel from WNS 1 2 PERSISTENT CONNECTION App Cloud Service WNS Request access token 3 Send Push Notification 4 WNS sends notification to device

Important Notes Device can be offline or disconnected. Success indicates that the request was successfully received by WNS; not necessarily that the user saw it. The server will cache and retry if the client reconnects within a certain time. Additional headers in the response for notification and device status.

Same APIs You screamed asked, we deliver: Raw to wake a task! Reliable during intermittent client connectivity issues Per type offline queue depth better suited to app needs End to end delivery significantly faster No more certificates to manage - OAuth!

Request a new URI at every app launch Renew your URI periodically (expire) OAuth requires App Identity in Store Can cross-use App Identity and SID/Secret *

*Note: Appx files signed with a Symantec cert cannot use WNS

Persist 7 days or less Up to 20 most recent notifications per app FIFO “More” notification Offline notification grouping

Windows Phone 8.0 and Windows Phone Silverlight 8.1 apps using MPN will be removed when the app is launched from the primary tile Windows Phone Silverlight 8.1 and Store apps using WNS are fully in charge of managing their own notifications

MechanismScenarioExpiresWinRT API Local Update a tile immediately, while the app is running or from a background task Never TileUpdateManager tileUpdater.Update() Scheduled Update a tile once, at a specific date and time. E.g., tomorrow at 4pm 3 days TileUpdateManager tileUpdater.AddToSchedule() Periodic Update a tile by polling a remote URI on an interval. E.g., every 30 minutes 3 days TileUpdateManager tileUpdater.StartPeriodicUpdate() Push Update a tile immediately, by sending a push notification from your server -or- Send a Raw notification to wake a background task that triggers a tile update 3 daysPushNotificationChannelManager
