A public action method ABC was not found on controller

Hi Everyone,

I've a controller within in which we have created following two actions:

public ActionResult DoSomething()
        {

            return View();
        }

[HttpPost]
public ActionResult DoSomething()
        {

            "do something and return Json result"
        }

Now the problem is that while a link point to the DoSomething action it gives me following exception:

A public action method 'DoSomething' was not found on controller

I've looked around for possible reasons for this however, most of the forums they say that most of the times it happens due to emitting headers, so add the verb:

[acceptverbs(httpget | header)]

Which I tried (though my code is not emitting any kind of header).

Would appreciated if someone could point me out on any other possible reasons.

My apologies as I forgot to mention that It happens only when we deploy the application on IIS, however on local Visual Studio development server it works fine.

Thanks & Regards
Pawan
