EnableOptimizations = true not minifying js only bundling

Question

to bundle and minify js code i have added following code

public static void RegisterBundles(BundleCollection bundles)
        {
            BundleTable.EnableOptimizations =true;
            bundles.Add(new ScriptBundle("~/bundles/app")
                 .Include("~/app/app.js")
                 .IncludeDirectory("~/app/Auth/", "*.js", searchSubdirectories: true)
                 .IncludeDirectory("~/app/Common/", "*.js", searchSubdirectories: true)
                   );

    }

and i have <compilation debug="true" targetFramework="4.5"/> in by web config.

But its only bundling the files not minifying..

can anyone tell where am wrong...?

Answer 1

要启用捆绑和最小化，应将web.config中的调试密钥设置为false值：

<compilation debug="false" targetFramework="4.5"/>

Answer 2

The bundle doesn't work in the debug mode. Thus, we set the debug value false in web.config file, as shown in the snippet, given below:

<system.web>  
   <compilation debug="false" targetFramework="4.5.1" />  
</system.web>
