ASP.NET MVC: Adding active tag for html elements

 public static MvcHtmlString SelectedLink(this HtmlHelper helper, string linkText, string actionName, string controlName, string activeClassName, int id)
        {
            if (helper.ViewContext.RouteData.Values["action"].ToString() == actionName &&
                    helper.ViewContext.RouteData.Values["controller"].ToString() == controlName)
                return helper.ActionLink(linkText, actionName, controlName, new { Class = activeClassName, Id = id });

            return helper.ActionLink(linkText, actionName, controlName);
        }

or 

        public static MvcHtmlString ActiveMenuItem(this HtmlHelper helper, string linkText, string actionName, string controllerName, int id)
        {
            TagBuilder li = new TagBuilder("li");

            RouteData routedata = helper.ViewContext.RouteData;
            string currentAction = routedata.GetRequiredString("action");
            string currentController = routedata.GetRequiredString("controller");
            int currentId = ConvertionHelper.GetConvertedValue<int>(routedata.GetRequiredString("id"));

            if (string.Equals(currentAction, actionName, StringComparison.OrdinalIgnoreCase) &&
                string.Equals(currentController, controllerName, StringComparison.OrdinalIgnoreCase) &&
                int.Equals(currentId, id))
            {
                li.AddCssClass("active");
            }

            li.InnerHtml = helper.ActionLink(linkText, actionName, new { Id = id }).ToHtmlString();

            return MvcHtmlString.Create(li.ToString());
        }

Areas duplicated: Multiple types were found that match the controller named 'Home'.

Problem:

Multiple types were found that match the controller named 'Home'. This can happen if the route that services this request ('{controller}/{action}/{id}') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.

The request for 'Home' has found the following matching controllers:
Project.Web.Controllers.HomeController
Project.Web.Areas.Dashboard.Controllers.HomeController

Solution:

In Global.asax

    routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                new string[] { "Project.Web.Controllers" }
            );
