Problems with references and MVC

I have a project where it works. I needed to create another project elsewhere and I was enjoying what I already have. It turns out that it is giving an error in base.Initialize (...) saying that it does not recognize this face. I put the same using the other project, that is, ctrl + c and ctrl + v and nothing else. Below my methods

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
        {

            requestContext.HttpContext.Response.Buffer = true;
            requestContext.HttpContext.Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
            requestContext.HttpContext.Response.Expires = 0;
            requestContext.HttpContext.Response.CacheControl = "no-cache";
            requestContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            string strPaginaAtual = requestContext.HttpContext.Request.CurrentExecutionFilePath;
            strPaginaAtual = strPaginaAtual.Remove(0, strPaginaAtual.LastIndexOf("/") + 1);

            base.Initialize(requestContext);

        }

        protected override void OnException(ExceptionContext filterContext)
        {

            base.OnException(filterContext);
        }

and my usings:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using System.Web.Security;

I was compiling and gave this error:

Error   1   'V99Util.WebPageBase.Initialize(System.Web.Routing.RequestContext)': no suitable method found to override
