mvc bundle功能（1）

现如今都提倡敏捷开发，快速开发，但是再要求速度的同时，还得保证质量！前端我是没办法，毕竟是直接要面向用户的，但是后台，解决方案那就多了，诸如extjs，bootstrap，kendoui，都可以解决。但是使用了这些第三方的东西，我们的后台是漂亮了，效果也炫了，新的问题就来了，大量的引用js、css。

这是我用bootstrap、kendoui搭的一个标准后台，代码非常简洁，但是引用了很多样式和js，加载完这个页面发送了又16个请求，耗时1.36s。

有没有一种方法可以把这些js和css合并起来并且压缩一下呢？这样我们的后台效果不就更好了吗？当然有，.net mvc自带的bundle功能。我们先看使用了该功能之后是什么效果

很明显，请求数减少了，响应时间也减少了，那我们来看看bundle到底是如何实现的。

 1 public class BundleConfig

79         }
80     }

首先需要首先需要配置Bundle

 1 public class MvcApplication : System.Web.HttpApplication
 2     {
 3         protected void Application_Start()
 4         {
 5             AreaRegistration.RegisterAllAreas();
 6
 7             WebApiConfig.Register(GlobalConfiguration.Configuration);
 8             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
 9             RouteConfig.RegisterRoutes(RouteTable.Routes);
10             BundleConfig.RegisterBundles(BundleTable.Bundles);
11             AuthConfig.RegisterAuth();
12         }
13     }

再全局注册Bundles
