Azure WebJobs QueueTrigger not triggering

Question

I'm trying to find what I'm doing wrong regarding an Azure WebJobs QueueTrigger method that should be triggered from an Azure Storage Queue.

I've read a couple of documents (as in blog posts / msdn articles). But I'm still not clear.

Main question / misunderstood aspect:

What should be the name of the connection string for Azure storage console app App.config or Windows Azure Configuration (portal). So far I have the following name set at both places.

AzureJobsStorage
AzureWebJobsStorage
AzureJobsRuntime
AzureJobsDashboard
AzureJobsData

Here's my WebJobs console app code.

static void Main()
{
    JobHost host = new JobHost();
    host.RunAndBlock();
}

public static void CreateLeague([QueueTrigger("temp")] string msg)
{
    var task = JsonConvert.DeserializeObject<QueueTask>(msg);

    if (task.TaskType == QueueTask.TaskTypes.Pdf)
      RenderPdf(task.Id);
}

This console app is continuously running on my Azure Website.

I can access its "debug" page where I can toggle output and I see it is started / running.

My code to add queue (from my ASP.NET MVC app):

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["StorageConnectionString"]);
CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();
CloudQueue queue = queueClient.GetQueueReference("temp");
queue.CreateIfNotExists();
Common.QueueTask task = new Common.QueueTask();
task.TaskType = Common.QueueTask.TaskTypes.Pdf;
task.Id = p.Id;
CloudQueueMessage msg = new CloudQueueMessage(JsonConvert.SerializeObject(task)      );
queue.AddMessage(msg);

This code is executed, and queue are added to my Storage Account. But they did not get "dequeue" or read from the WebJobs.

Hmm, the WebJobs class had to be public.

using Microsoft.Azure.WebJobs;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
using Newtonsoft.Json;
using Proceed.Common;
using System;
using System.Configuration;
using System.IO;

public class WebJobsTask {
  public static void Main()
  {
      JobHost host = new JobHost();
      host.RunAndBlock();
  }

  public static void CreateLeague([QueueTrigger("temp")] string msg)
  {
    var task = JsonConvert.DeserializeObject<QueueTask>(msg);

    if (task.TaskType == QueueTask.TaskTypes.Pdf)
      RenderPdf(task.Id);
  }
}
