很高兴，最近项目用到了Asp.Net MVC4 + Entity Framework5，发现mvc4加入了Bundle、Web API等技术，着实让我兴奋，以前是用第三方的，这里主要说说Bundle技术。
很多大网站都没有用Bundle技术造成很多资源浪费与性能的牺牲，别小瞧 用上了你会发现他的好处：
将多个请求捆绑为一个请求，减少服务器请求数
没有使用Bundle技术，debug下看到的是实际的请求数与路径
使用Bundle技术，并且拥有缓存功能
调试设置为Release模式并按F5或修改web.config，就可以看到合并与压缩的效果
压缩javascript，css等资源文件，减小网络带宽，提升性能
后台配置
MVC4在架构上有些变动，简化了原来的Global.asax，增加了一些静态的配置文件在App_Start下面，留意下BundleConfig.cs，顾名思义是Bundle的配置，所有它的配置在这里进行就可以了，当然也可以单独的配置文件。
代码如下: public class BundleConfig { // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkId=254725 public static void RegisterBundles(BundleCollection bundles) { 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*")); // 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 StyleBundle("~/Content/css").Include("~/Content/site.css")); bundles.Add(new StyleBundle("~/Content/themes/base/css").Include( "~/Content/themes/base/jquery.ui.core.css", "~/Content/themes/base/jquery.ui.resizable.css", "~/Content/themes/base/jquery.ui.selectable.css", "~/Content/themes/base/jquery.ui.accordion.css", "~/Content/themes/base/jquery.ui.autocomplete.css", "~/Content/themes/base/jquery.ui.button.css", "~/Content/themes/base/jquery.ui.dialog.css", "~/Content/themes/base/jquery.ui.slider.css", "~/Content/themes/base/jquery.ui.tabs.css", "~/Content/themes/base/jquery.ui.datepicker.css", "~/Content/themes/base/jquery.ui.progressbar.css", "~/Content/themes/base/jquery.ui.theme.css")); } }新闻热点
