With the newer Android APIs, they now require a notification channel (NotificationChannel) to be used. You can do fairly easily by using NotificationCompat from the Android support library and only creating the channel if you are on Oreo or later.

NotificationCompat w/ Channel Example:

using (var notificationManager = NotificationManager.FromContext(ApplicationContext))
{
    var channelName = GetText(Resource.String.notificationChannelNormal);
    if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
    {
        NotificationChannel channel = null;
        #if !DEBUG
        channel = notificationManager.GetNotificationChannel(channelName);
        #endif
        if (channel == null || resetChannel)
        {
            channel = new NotificationChannel(channelName, channelName, NotificationImportance.Low)
            {
                LockscreenVisibility = NotificationVisibility.Public
            };
            channel.SetShowBadge(true);
            notificationManager.CreateNotificationChannel(channel);
        }
        channel.Dispose();
    }
    Bitmap bitMap = BitmapFactory.DecodeResource(Resources, Resource.Drawable.ic_launcher);
    var notificationBuilder = new NotificationCompat.Builder(ApplicationContext)
                                                    .SetContentTitle(title)
                                                    .SetContentText(message)
                                                    .SetSmallIcon(Resource.Drawable.ic_stat_notification_network_locked)
                                                    .SetLargeIcon(bitMap)
                                                    .SetShowWhen(false)
                                                    .SetChannelId(channelName)
                                                    .SetContentIntent(pendingIntent);
    return notificationBuilder.Build();
}
