UWP push notifications

UWP (Universal Windows Platform) applications can receive push notifications using the Windows Push Notification Services (WNS). WNS allows you to send notifications from a backend server to your UWP app running on Windows devices. Here's an overview of the steps involved in implementing push notifications for a UWP app:

1. Create a Windows Developer Account: To use WNS, you need a Windows Developer Account. If you don't have one, sign up at the Microsoft Developer Dashboard: https://developer.microsoft.com/en-us/dashboard.

2. Register your App with WNS: Register your UWP app with WNS to obtain a package security identifier (SID) and a client secret. This will allow your backend server to authenticate with WNS and send notifications on behalf of your app.

3. Configure the App Manifest: In your UWP project's Package.appxmanifest, add the necessary capabilities and extensions for push notifications. Set the ToastCapable and Notification capabilities to "true", and configure the WindowsRuntimeAccess extension for "allTrusted". This allows your app to receive toast notifications.

4. Handle Push Notifications in the App: Implement the necessary code in your UWP app to handle push notifications when they arrive. You can use the Windows.Networking.PushNotifications namespace to subscribe to push notifications and handle events.

5. Send Notifications from Backend Server: On your backend server, use the package SID and client secret obtained earlier to authenticate with WNS. Send push notifications using HTTP POST requests to the WNS endpoint for your app.

6. Handle Push Notification on the Server: Optionally, you can implement code on your server to handle push notification-related events, such as device registration and sending notifications.

Microsoft provides documentation and code samples to help you implement push notifications in your UWP app. For more detailed steps and code examples, refer to the official Microsoft documentation:

• UWP push notifications overview: https://docs.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/windows-push-notification-services--wns--overview
• UWP push notifications code sample: https://github.com/Microsoft/Windows-universal-samples/tree/main/Samples/PushAndPeriodicNotifications

Make sure to follow Microsoft's guidelines and best practices when implementing push notifications to ensure a smooth and secure experience for your UWP app users.
