How to send notification from C# Console application

Here is the code to send notification using C#, I have made it working

 WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
                        tRequest.Method = "post";
                        tRequest.ContentType = "application/json";
                        var objNotification = new
                        {
                            to = notification.DeviceToken,
                            data = new
                            {
                                title = notification.NotificationTitle,
                                body = notification.NotificationBody
                            }
                        };
                        string jsonNotificationFormat = Newtonsoft.Json.JsonConvert.SerializeObject(objNotification);

                        Byte[] byteArray = Encoding.UTF8.GetBytes(jsonNotificationFormat);
                        tRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
                        tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
                        tRequest.ContentLength = byteArray.Length;
                        tRequest.ContentType = "application/json";
                        using (Stream dataStream = tRequest.GetRequestStream())
                        {
                            dataStream.Write(byteArray, 0, byteArray.Length);

                            using (WebResponse tResponse = tRequest.GetResponse())
                            {
                                using (Stream dataStreamResponse = tResponse.GetResponseStream())
                                {
                                    using (StreamReader tReader = new StreamReader(dataStreamResponse))
                                    {
                                        String responseFromFirebaseServer = tReader.ReadToEnd();

                                        FCMResponse response = Newtonsoft.Json.JsonConvert.DeserializeObject<FCMResponse>(responseFromFirebaseServer);
                                        if (response.success == 1)
                                        {
                                            new NotificationBLL().InsertNotificationLog(dayNumber, notification, true);
                                        }
                                        else if (response.failure == 1)
                                        {
                                            new NotificationBLL().InsertNotificationLog(dayNumber, notification, false);
                                            sbLogger.AppendLine(string.Format("Error sent from FCM server, after sending request : {0} , for following device info: {1}", responseFromFirebaseServer, jsonNotificationFormat));

                                        }

                                    }
                                }

                            }
                        }

Here is class FCMResponse used in this code to store response sent from FMServer

 public class FCMResponse
{
    public long multicast_id { get; set; }
    public int success { get; set; }
    public int failure { get; set; }
    public int canonical_ids { get; set; }
    public List<FCMResult> results { get; set; }
}
  public class FCMResult
{
    public string message_id { get; set; }
}
