ASP.NET MVC - using the same form to both create and edit

Question

Whats the best practice approach to creating a form that is used to both create new models and edit existing models?

Are there any tutorials that people can point me in

Answer 1

I use something like

[HttpGet]
public ActionResult EntityEdit(Guid id)
{
    return View();
}

and

[HttpGet]
public ActionResult EntityCreate()
{
   return View("EntityEdit");
}

That seems to work OK.
