ASP.NET Code Challenge: Not sure how the Content Detail method is not returning the Content method.

I was working on the code challenge below:

Update the provided VideoGamesController.Detail action method to use ActionResult for its return type instead of a string. In the action method, return the result of a call to the base controller's Content method. Keep the content the same by passing the string literal "Welcome to the Video Game Detail page!" to the Content method.

This is the code it starts with:

using System.Web.Mvc;

namespace Treehouse.Controllers
{
    public class VideoGamesController : Controller
    {
        public ActionResult Detail()
        {
            return new ContentResult() { Content = "Welcome to the Video Game Detail page!"};
        }
    }
}

Below is my answer but I get the following Error which I believe I am handling correctly:
Bummer! In the 'Detail' method, are you returning a call to the 'Content' method?

using System.Web.Mvc;

namespace Treehouse.Controllers
{
    public class VideoGamesController : Controller
    {
        public ActionResult Detail()
        {
            return new ContentResult() { Content = "Welcome to the Video Game Detail page!"};
        }
    }
}

My detail method "public ActionResult Detail()" has in its return the ContentResult() which is inherited from ActionResult so creating object here should work as it does int the previous example from the lesson. Any ideas what I am missing here?

When you call a method, the parentheses come after the method name..

Also, any argument(s) being passed to the method will go inside those parentheses. And you won't need new because you're not instantiating a class object, just making a simple function call.

I now see what I was doing wrong. below is a summary of what I needed to change :

return Content("Welcome to the Video Game Detail page!");

In the example from the instructor I had used what I previous and had the same result but it is no in fact using the method call as instructed. Thanks for the explanation.

using System.Web.Mvc;

namespace Treehouse.Controllers

public class VideoGamesController: Controller
{
public string Detail()
{
return "Welcome to the Video Game Detail page!";

}
