I'm trying to use MVC 4's bundling and optimization features. They seem more standard and easier to use then client dependency's options.

I updated umbracoReservedPaths with the virtual path that I used in bundling.

Then updated the global.asax with:

RouteConfig.RegisterRoutes(RouteTable.Routes);

And created the following class in App_Start.

    public class BundleConfig
    {
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                "~/scripts/jquery-1.9.1.js", 
                "~/scripts/bootstrap.min.js"));

            bundles.Add(new StyleBundle("~/bundles/baseCSS").Include(
                "~/Content/bootstrap.css",
                "~/Content/bootstrap-responsive.css"
                ));
        }
    }

Now my masterlayout.cshtml contains:

@using System.Web.Optimization
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@{
    Layout = null;
}

@Styles.Render("~/bundles/baseCSS")

But it just renders out a url and not the actual files.

Ideas?
