How do I add BundleConfig.cs to my project?

Question

I have an ASP.Net MVC project and I want to implement bundling, but everything I can find on the internet directs me to open BundleConfig.cs in App_Start - however this file does not exist in my project. I have only three files in that folder: FilterConfig, RouteConfig and WebApiConfig.

Bundle config wasn't generated when I created the solution (IIRC it was a blank ASP.NET MVC project at the beginning).

It seems like this should be really easy to do, but I just plain cannot figure it out.

P.S. Just to clarify to those not reading closely, this is for a MVC4/.Net 4.5 app created from scratch. The solution is marked below.

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization 

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web; using System.Web.Optimization;  namespace CodeRepository.Web {     public class BundleConfig     {         // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862         public static void RegisterBundles(BundleCollection bundles)         {             bundles.Add(new ScriptBundle("~/bundles/jquery").Include(                         "~/Scripts/jquery-{version}.js"));              bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(                         "~/Scripts/jquery.validate*"));              // Use the development version of Modernizr to develop with and learn from. Then, when you're             // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.             bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(                         "~/Scripts/modernizr-*"));              bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(                       "~/Scripts/bootstrap.js",                       "~/Scripts/respond.js"));              bundles.Add(new StyleBundle("~/Content/css").Include(                       "~/Content/bootstrap.css",                       "~/Content/site.css"));         }     } } 

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;  protected void Application_Start() {     AreaRegistration.RegisterAllAreas();     RouteConfig.RegisterRoutes(RouteTable.Routes);     BundleConfig.RegisterBundles(BundleTable.Bundles); }
