The document provides an overview of the Azure Notification Hub, detailing how it enables developers to send push notifications to users across multiple platforms. It explains the setup process, device token management, and the efficient handling of notifications through tag-based routing. Additionally, it discusses features like scheduling notifications and provides code examples for integration with various backend technologies.

3. • Push Notifications offer developers a way
to send timely information relating to
their applications even when they are not
running
• Push notifications are delivered through
platform-specific infrastructures called
Platform Notification Systems (PNS)
+Windows has the unique ability to
provide the end user glanceable access
to the information they care most about,
via Live Tiles

var channel = await
PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();
await hub.RegisterNativeAsync(channel.Uri);
• Add Nuget package WindowsAzure.Messaging.Managed
• Set Toast capable in .appxmanifest
• Create and register Notification
Channel in app.xaml.cs

17. • Add Nuget package WindowsAzure.ServiceBus
• Create the hub
• Send native notifications

20. • What if we want more granular control over notifications?
• If we want to push notifications only to people who are subscribed to
a specific category, we use tags.
App
Backend
Combine tags with AND (&&), OR (||), NOT (!) and parentheses.
Tag expressions are limited to 20 tags if they contain only ORs; otherwise they are limited to 6 tags

await hub.SendWindowsNativeNotificationAsync(toast, "phone");
await hub.SendWindowsNativeNotificationAsync(toast, "phone && news");
await hub.SendWindowsNativeNotificationAsync(toast, "phone || news");

21. • When in Standard tier, Notification Hubs supports a feature that
enables you to schedule notifications up to 7 days in the future
• To cancel a scheduled notification
There are no limits on the number of scheduled notifications you can send
