Azure WebJobs - Can I use Async Methods?

Question

I was wondering if the Azure WebJobs SDK can trigger async methods? Currently I have a method that looks like the following:

class Program {     static void Main(string[] args)     {         var host = new JobHost();         host.RunAndBlock();     }      public static void ProcessStuff([QueueInput("myqueue")] string msg)     {         var tsk = ProcessStuffAsync(msg)                   .ContinueWith(x => HandleAsyncError(x),                       TaskContinuationOptions.OnlyOnFaulted);         tsk.Wait();     }      public static async Task ProcessStuffAsync(string msg)     {         // do some async stuff and await it     }      // other methods ... } 

However, I was wondering if I could just have the JobHost know to call my async method instead? There's not a ton of documentation out there on trying to use async/await in WebJobs, and it would be really nice if I could.

I'm trying to run this locally to test ... but the WebJobs SDK doesn't support the local Storage Emulator...

UPDATE 4/7/2014: Victor's answer is correct, but I did want to show what you'll see from using async methods in a WebJob (they do work).

For a method in your WebJob that looks like the following:

public async static Task ProcessMessageAsync([QueueInput("testq2")] string message) {     await Task.Delay(50);      Console.WriteLine("Processing Message Async...");     Console.WriteLine(message); } 

You will see the following output in your WebJobs log:

running in pid: 6272 Timestamp:4:36:02 PM Parameters bound. Invoking user function. -------- Warning: This asynchronous method will be run synchronously. Processing Message Async... a test message -------- Success

Async is now supported. See the blog post here.

Unfortunately, the short answer to both questions is: not supported.

(slightly) longer answer:

WebJobs SDK does not support async methods. If you look in the execution log (on the dashboard) you will see a warning saying that async functions (functions that return Task or Task<>) are executed synchronously.

We don't support the local emulator. You have to use a real Storage Account when developing.
