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

A bit late to the party. But it seems like no one has mentioned
bundling & minification of StyleBundle, so..

@Styles.Render("~/Content/css") 

calls in Application_Start():

BundleConfig.RegisterBundles(BundleTable.Bundles);            

which in turn calls

public static void RegisterBundles(BundleCollection bundles)
{
    bundles.Add(new StyleBundle("~/Content/css").Include(
              "~/Content/bootstrap.css",
              "~/Content/Site.css"));
}

RegisterBundles() effectively combines & minifies bootstrap.css & Site.css
into a single file,

But..

only when debug is set to false in Web.config.
Otherwise bootstrap.css & Site.css will be served individually.
Not bundled, nor minified:
