Long running method in controller action - MVC [duplicate]

Question

I have a method similar to the following in WebAPI - MVC

public IActionResult Post(Model model)
{
      ALongRunningMethod();
      return Ok();
}

I have two options.

1. Wait for the method to complete. But, what if its too long ? Doesn't the API timeout ?
2. Run that in a separate thread using Tasks but return Ok (200 HTTP Code) immediately ? What if some exception occur in that long running method ?

Totally confused. What should I do in this case ?

Starting from .Net 4.5.2, you now have QueueBackgroundWorkItem to deal with long running operations in ASP.Net.
