Consider NoContent action result method on Controller

[PradeepKadubandi]

This came up while I and Ryan were briefly discussing code to be generated for Web API scaffolding, it may be handy to define NoContent action result method on Controller class.

This is already implemented @PradeepKadubandi

    public IActionResult index() {
        return new NoContentResult();
    }

Is this what you are looking for?

I would imagine this is about having a helper factory method on the Controller base class, just like there is for many other result types.
