ASP.Net MVC3 - Properly handle Ajax form submission on the server side
I have a form that I would like to endow with wonderful Ajax-submission goodness

    @using(Html.BeginForm()) {
      ...
    }

I changed `Html.BeginForm()` to `Ajax.BeginForm()` but am not quite clear about what to do on the server side. 

Previously, I used to do something like this:

    [HttpPost]
    public ActionResult EditMyStuff(MyViewModel vm) {
      if(!ModelState.IsValid)
        return View(vm);
    
      // save stuff
      return RedirectToAction("Index");         
    }

And this is stuff I want to retain if the client has javascript disabled but if the form is submitted via Ajax clearly this is not what I want - I want any errors to appear in the validation summary on error or an "Your changes have been saved" message on success.

What is the standard way of doing this?
