asp.net-optimization

I wonder what I don't do correct here. I am using ASP.NET C# MVC4 and I want to take use of new css/js optimization feature. Here is my HTML part @Styles.Render("~/content/css") Here is my BunduleConfig.cs part bundles.Add(new StyleBundle("~/content/css").Include( "~/content/css/reset.css", "~/content/css/bla.css")); // BundleTable.EnableOptimizations = true; Output (works): <link href="/content/css/reset.css" rel="stylesheet"/> <link href="/content/css/bla.css" rel="stylesheet"/> However when I uncomment BundleTable.EnableOptimizations = true; html output looks like this <link href="/content

In MVC 4 we have bundles. While defining the bundles we can use wildcards like * for all files in a folder. In the example below what does -{version} mean? public static void RegisterBundles(BundleCollection bundles) { bundles.Add(new ScriptBundle("~/bundles/jquery").Include( "~/Scripts/jquery-{version}.js")); } Hao Kung The -{version} basically maps to a version regex , or to be precise: (\d+(?:\.\d+){1,3}) . Using * tends to grab too much, for example if you bundle jquery* , that will include jquery-ui as well which might mess up the ordering. But using jquery-{version}.js would let you

How does @Scripts.Render("~/bundles/jquery") differ from just referencing the script from html like this <script src="~/bundles/jquery.js" type="text/javascript"></script> Are there any performance gains? Bundling is all about compressing several JavaScript or stylesheets files without any formatting (also referred as minified) into a single file for saving bandwith and number of requests to load a page. As example you could create your own bundle: bundles.Add(New ScriptBundle("~/bundles/mybundle").Include( "~/Resources/Core/Javascripts/jquery-1.7.1.min.js", "~/Resources/Core/Javascripts

... or how I learned to stop worrying and just write code against completely undocumented APIs from Microsoft . Is there any actual documentation of the official System.Web.Optimization release? 'cuz I sure can't find any, there's no XML docs, and all the blog posts refer to the RC API which is substantially different. Anyhoo.. I am writing some code to automatically resolve javascript dependencies and am creating bundles on the fly from those dependencies. Everything works great, except if you edit scripts or otherwise make changes that would affect a bundle without restarting the application
