Xamarin.iOS 8 push notifications

With iOS 8+ the way you register for push notifications has changed a bit. So if you want your app to continue receiving push notifications on iOS 8 and above you will need to adjust your registration to this:

var settings = UIUserNotificationSettings.GetSettingsForTypes(UIUserNotificationType.Sound    | UIUserNotificationType.Alert | UIUserNotificationType.Badge, null);UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);UIApplication.SharedApplication.RegisterForRemoteNotifications();

To continue supporting iOS7 and bellow you can still register as before or just use the lines bellow:

if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0)){    var settings = UIUserNotificationSettings.GetSettingsForTypes(UIUserNotificationType.Sound        | UIUserNotificationType.Alert | UIUserNotificationType.Badge, null);    UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);    UIApplication.SharedApplication.RegisterForRemoteNotifications();}else{    const UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert                                                       | UIRemoteNotificationType.Badge                                                       | UIRemoteNotificationType.Sound;    UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);}

Conclusion

I stumbled over this one as I was following along the Azure push notification hub tutorial. Hope it will be of some help to you.
