Call an action method from a layout in ASP.NET MVC

I have one layout and one partial view that are in the shared folder. In a partial view, top menu items that are not static are presented. Therefore, I need to call an action method to get menu items from the database. To do this, I created a controller and added an action method to it.

When I try to view the page in a web browser, this error occurred:

Controller for path '/' not found or does not implement IController.

Note: I tried the Html.RenderAction, Html.Partial methods too ... And I tried to create another view folder and create a new partial view and a new controller named with the suffix "folder name + controller".

Markup:

<!DOCTYPE html>
<html>
<head>
    <title>@ViewBag.Title</title>
</head>
<body>
    <div id="header">
        @Html.Action("~/Views/Shared/_TopMenu.cshtml", "LayoutController", new {area =""}); //Here is the problem.

    </div>
   <div>
        @RenderBody();
   </div>

</body>
</html>

_TopMenu.cshtml:

@model IList<string>

@foreach (string item in Model)
{
    <span>item</span>
}

LayoutController ( Controllers):

 public class LayoutController : Controller
    {
        //
        // GET: /Shared/
        public ActionResult Index()
        {
            return View();
        }

        [ChildActionOnly]
        [ActionName("_TopMenu")]
        public ActionResult TopMenu()
        {
           IList<string> menuModel = GetFromDb();
           return PartialView("_TopMenu", menuModel);
        }    
    }
