To use push notifications in Xamarin Forms, you must first configure a push notification provider, such as Firebase Cloud Messaging or Apple Push Notification provider (APNS). After that, you can proceed as follows: Make a cross-platform Xamarin Forms application. Incorporate the push notification service SDK into your application. Register the application with the push notification service, providing relevant information such as the application ID, certificate, and permissions. Set up a notification center to manage push notifications for your application. Add code to your application to handle push notifications. This usually entails registering a device with the notification hub and configuring event handlers to respond to incoming push notifications.
