ASP.NET MVC 2 ошибка при использовании RenderAction : The controller for path '/' was not found or does not implement IController.

При использовании RenderAction в ASP.NET MVC view:

<%Html.RenderAction("BrowserVersion", "HomeController"); %>

Получаем ошибку:

The controller for path '/' was not found or does not implement IController.

Ниже приведен фрагмент кода HomeController-а:

public class HomeController : Controller
{

 [ChildActionOnly]
 public ActionResult BrowserName()
 {
     ViewData["BrowserName"] = Request.Browser.Browser;
     return View();
 }

}
