Regarding Push notification

public void SendPush(string deviceToken, string message, string baseurl)
{
    if (!string.IsNullOrEmpty(deviceToken))
    {
        var push = new PushBroker();
        //Wire up the events for all the services that the broker registers
        push.OnNotificationSent += NotificationSent;
        push.OnChannelException += ChannelException;
        push.OnServiceException += ServiceException;
        push.OnNotificationFailed += NotificationFailed;
        push.OnDeviceSubscriptionExpired += DeviceSubscriptionExpired;
        push.OnDeviceSubscriptionChanged += DeviceSubscriptionChanged;
        push.OnChannelCreated += ChannelCreated;
        push.OnChannelDestroyed += ChannelDestroyed;
        try
        {
            string ss = HostingEnvironment.MapPath(@"~\Resources\Certificates2.p12");
            var appleCert = File.ReadAllBytes(ss);
            push.RegisterAppleService(new ApplePushChannelSettings(false, appleCert, "123"));
            push.QueueNotification(new AppleNotification()
            .ForDeviceToken(deviceToken)//the recipient device id
            .WithAlert(message)//the message
            .WithBadge(5)
            .WithSound("snap audio alert.mp3")
                // .WithSound("default")
