The type or namespace name 'ScriptBundle' could not be found (are you missing a using directive or an assembly reference?)

Question

using System.Web;
using System.Web.Optimization;

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                    "~/Scripts/jquery-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                    "~/Scripts/jquery-ui-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/Scripts/jquery.unobtrusive*",
                    "~/Scripts/jquery.validate*"));

I am getting the error:

Error   16  The type or namespace name 'ScriptBundle' could not be found (are you missing a using directive or an assembly reference?)

Looks like some reference issue, but i am not able to figure it out. Please help. What could be causing this error?

[This](http://stackoverflow.com/questions/9475893/how-to-add-reference-to-system-web-optimization-for-mvc-3-converted-to-4-app) may give a hint, you need to reference `System.Web.Optimization.dll`. — Joachim Isaksson, May 28 '13 at 03:36
Thanks Joachim, but it already has that reference using System.Web.Optimization. May be looks like i will have to uninstall the reference and it back again. — Vijay Pote, May 28 '13 at 04:07

I got this error when I was upgrading an MVC3 project to MVC4. I was missing the reference to System.Web.Optimization.dll which is in the NuGet package Microsoft ASP.NET Web Optimization Framework (Microsoft.AspNet.Web.Optimization).
