class Program
    {
        // Please set the following connection strings in app.config for this WebJob to run:
        // AzureWebJobsDashboard and AzureWebJobsStorage
        static void Main()
        {
            var config = new JobHostConfiguration();

            {
                config.UseDevelopmentSettings();

            config.Queues.BatchSize = 8;
            config.Queues.MaxDequeueCount = 3;
            config.Queues.VisibilityTimeout = TimeSpan.FromSeconds(5);
            config.Queues.MaxPollingInterval = TimeSpan.FromSeconds(3);


            var host = new JobHost(config);
            // The following code ensures that the WebJob will be running continuously
            host.RunAndBlock();
        }
    }

 public class Functions
    {
        // This function will get triggered/executed when a new message is written 
        // on an Azure Queue called queue.
        public static void ProcessQueueMessage([QueueTrigger("queue")] string message, TextWriter log)
        {
            log.WriteLine(message);
            throw new Exception("There was an error processing the message");
        }
