You can use PushSharp which is a nuget package which support push notification for Apple and also for Google and Microsoft.

Here are the links to github and nuget.

This is a sample to send push notification for Apple:

// Configuration (NOTE: .pfx can also be used here)
var config = new ApnsConfiguration (ApnsConfiguration.ApnsServerEnvironment.Sandbox, 
"push-cert.p12", "push-cert-pwd");

// Create a new broker
var apnsBroker = new ApnsServiceBroker (config);

// Wire up events
apnsBroker.OnNotificationFailed += (notification, aggregateEx) => {

aggregateEx.Handle (ex => {

    // See what kind of exception it was to further diagnose
    if (ex is ApnsNotificationException) {
        var notificationException = (ApnsNotificationException)ex;

        // Deal with the failed notification
        var apnsNotification = notificationException.Notification;
        var statusCode = notificationException.ErrorStatusCode;

        Console.WriteLine ($"Apple Notification Failed: ID={apnsNotification.Identifier}, Code={statusCode}");

    } else {
        // Inner exception might hold more useful information like an ApnsConnectionException           
        Console.WriteLine ($"Apple Notification Failed for some unknown reason : {ex.InnerException}");
    }

        // Mark it as handled
        return true;
    });
};

    apnsBroker.OnNotificationSucceeded += (notification) => {
    Console.WriteLine ("Apple Notification Sent!");
};

// Start the broker
apnsBroker.Start ();

foreach (var deviceToken in MY_DEVICE_TOKENS) {
// Queue a notification to send
apnsBroker.QueueNotification (new ApnsNotification {
    DeviceToken = deviceToken,
    Payload = JObject.Parse ("{\"aps\":{\"badge\":7}}")
    });
}

// Stop the broker, wait for it to finish   
// This isn't done after every message, but after you're
// done with the broker
apnsBroker.Stop ();
