Issue in Global.asax.cs page in MVC4

Question

I my ASP.NET MVC 4 Project, my Global.asax.cs page shows the error on

 WebApiConfig.Register(GlobalConfiguration.Configuration); 

The name 'GlobalConfiguration' does not exist in the current context

I have done many controllers and Views and all... How can I solve this issue and recover my project?

Here is the rest of my code for context

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Http; using System.Web.Mvc; using System.Web.Routing;  namespace ..... {     // Note: For instructions on enabling IIS6 or IIS7 classic mode,      // visit http://go.microsoft.com/?LinkId=9394801     public class MvcApplication : System.Web.HttpApplication     {         protected void Application_Start()         {             AreaRegistration.RegisterAllAreas();              WebApiConfig.Register(GlobalConfiguration.Configuration);             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);             RouteConfig.RegisterRoutes(RouteTable.Routes);         }     } }

Make sure you have assembly System.Web.Http.WebHost.dll referenced. This is where GlobalConfiguration is.
