Styles.Render in MVC4

Question

In a .NET MVC4 project how does @Styles.Render works?

I mean, in @Styles.Render(\"~/Content/css\") which file is it calling?

Answer 1

As defined in App_start.BundleConfig, it's just calling

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

Nothing happens even if you remove that section.
