ASP.NET MVC: Performance Optimization with Bundling and Minification

How to Optimize performance using Bundling and Minification with ASP.NET Identity MVC 5 using C#, Entity Framework Code First

Bundling and minification are two techniques you can use in ASP.NET 4.5 to improve request load time. Bundling and minification improves load time by reducing the number of requests to the server and reducing the size of requested assets (such as CSS and JavaScript)

Step 1: Change BundleConfig class as below

public class BundleConfig
    // For more information on bundling, visit
    public static void RegisterBundles(BundleCollection bundles)
        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(

        bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(

        // Use the development version of Modernizr to develop with and learn from. Then, when you're
        // ready for production, use the build tool at to pick only the tests you need.
        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(

        bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(

        bundles.Add(new StyleBundle("~/Content/css").Include(

        bundles.Add(new StyleBundle("~/login/css").Include(

        bundles.Add(new ScriptBundle("~/login/js").Include(

Step 2: Change Login view as below

@using MvcDemo.Models
@model LoginViewModel
    ViewBag.Title = "Log in";
    Layout = null;

<!DOCTYPE html>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <!-- Tell the browser to be responsive to screen width -->
    <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport">
