Is there a way to send multiple notification to a NotificationHub with Webjob SDK?

Question

I have set up a WebJob that sends a notification to a NotificationHub every minute for test purposes and I would need it to send multiple notifications instead of just the one.

I have tried to just send an array of Notification objects instead of just the one object but this doesn't seem to work.

Function.cs

public class Functions
    {
        // This function will get triggered/executed when a new message is written 
        // on an Azure Queue called queue.
        public static void SendNotif1([TimerTrigger("0 * * * * *")] TimerInfo time, TextWriter log, [NotificationHub] out Notification notification)
        {
            string title = "Hello";
            string message = "Message";

            notification = new GcmNotification(ToGcmPayload(title, message));
        }

        private static string ToGcmPayload(string title, string message)
        {
            var gcmPayloadModel = new
            {
                data = new
                {
                    FormType = "Next scheduler",
                    MemberForm = "Hello"
                }
            };

            return JsonConvert.SerializeObject(gcmPayloadModel);
        }
    }

Am I trying to do this the wrong way ?

Not sure if you meant to send that code snippet or not, but I found the original source.

        // This binding sends multiple push notification to any clients registered with the template
    // when method successfully exits.
    public static void SendNotificationsOnTimerTrigger(
        [TimerTrigger("*/30 * * * * *")] TimerInfo timerInfo,
        [NotificationHub] out Notification[] notifications)
    {
        notifications = new TemplateNotification[]
            {
                GetTemplateNotification("Message1"),
                GetTemplateNotification("Message2")
            };
    }

    private static IDictionary<string, string> GetTemplateProperties(string message)
    {
        Dictionary<string, string> templateProperties = new Dictionary<string, string>();
        templateProperties["message"] = message;
        return templateProperties;
    }

I don't have the rep to comment but I believe as per this issue the above solution only works with the version 1 type functions, not version 2
