Async ctp MVC4 and workflows

Question

I have the below code which calls a workflow. I am wondering if I can changed the controller to be asynchronous using the async ctp.

public ActionResult Index()

We can use the TAP pattern for invoking windows workflow as follows - (Details are mentioned in my blog post http://tweetycodingxp.blogspot.com/2013/06/invoke-workflow-wf-using-task-based.html)

public async Task Index(string id)
{
    var wfInputArgs = new Dictionary
    {
        ...
    };

    var wfOutputArgs = await Task>.Factory.StartNew(
        () => WorkflowInvoker.Invoke(new MyWorkflow(), wfInputArgs));
    var result = wfOutputArgs["Output1"] as IEnumerable;
    ...
    return View(model);
}
