Umbraco MVC 4 System.Web.Http assembly missing

Question

So I installed Umbraco CMS in an empty MVC 5 application, got it to work, then when I tried to add a MVC 5 controller I realized Umbraco only supports < MVC 4, so the controller replaced the reference and stopped working.

Started a new MVC 4 project and installed Umbraco CMS, but then when I try to build I get the following error:

The type or namespace name 'HttpConfiguration' could not be found (are you missing a using directive or an assembly reference?) in WebApiConfig.cs file.

I have the reference System.Web.Http added correctly (v4.0, runtime version 4.0.30319) but in the WebApiConfig.cs file it somehow finds the class yet still think it's wrong:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;

namespace MyProj
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

Any idea what could be wrong?

Thanks in advance

EDIT:

I updated my NuGet packages and now it works. I think it was the System.Web.Mvc.dll that needed an update, although it changed the Web.config to point to the wrong version. After altering that, it worked.

Sometimes its best just to remove System.Web.Http as a reference then add it again as a quick fix then do clean and rebuild.

Also you could try going into the properties of System.Web.Http and changing specific version to false.

Failing that I would look into the web.config binding redirects.

Hope that helps.
