Warum "MapRoute" für "Standard" -Routing verwenden, während "MapHttpRoute" für "DefaultApi" -Routing verwendet wird?
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}"
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
