如何在ASP.NET MVC中同时运行两个功能而又不会彼此暂停

Question

I am using an SMS web service panel . In controller action HttpPost I call a method for sending SMS. I want to run this function simultaneously but I don't want to use async thread . Because first method is paused . Sending SMS is not important and if it failed to connect SMS web service I don't want to paused main action. How can I run these two methods simultaneously?

[HttpPost]
[ValidateAntiForgeryToken]
public JsonResult ServicesRes(FormCollection collection)
{

    .
    .
    .

    sendSMS();

    ....

    return Json(result, JsonRequestBehavior.AllowGet);


}

[UPDATE]
I tried async but not work
Main Action:

[HttpPost]
[ValidateAntiForgeryToken]
public JsonResult ServicesRes(FormCollection collection)
{

    .
    .
    .

    await sendSMS();

    ....

    return Json(result, JsonRequestBehavior.AllowGet);


}

//Send SMS

private async Task sendSMS()
{
      ...
      await Task.FromResult(0);
}

You need to use kind of Asynchronous programming here, for example this code run a thread without blocking current execution.

System.Threading.Tasks.Task task = new Task(()=>
            {
                sendSMS();
            });
            task.Start();

In c# you can also make your sendSMS async. for example like this

 public async Task sendSMS()
        {
            return;
        }
