FireBased pushnotification fcmClient.SendAsync(message,cancellationToken) returning null RRS feed

  • Question

  • For the IOS push notifications I am using below code and running from c#.net windows servervice

          var settings = FileBasedFcmClientSettings.CreateFromFile("c:\\fcm.json");
                // Construct the Client:
                using (var client = new FcmClient(settings))
                    var notification = new Notification
                        Title = "message_tobeSent",
                        Body = "message_tobeSent",//change later
                    // The Message should be sent to the News Topic:
                    var message = new FcmMessage()
                        ValidateOnly = false,
                        Message = new Message
                            Notification = notification,
                            Token = token //dynamic value
                    // Finally send the Message and wait for the Result:
                    CancellationTokenSource cts = new CancellationTokenSource();
                    // Send the Message and wait synchronously:
                    var result = client.SendAsync(message, cts.Token).Result;

    From the above code following line of code returning the null value

    "client.SendAsync(message, cts.Token)"

    If I run the same code from console app its working.

    Please suggest me, what i am missing?

  • Hi Naveen Gade,

    According to your description and relevance code, I am not what is FcmClient, is it a class in 3rd-party library, if so, I would suggest that you could post on 3rd-party forum for suitable support.
