This is because the default route that's used with new MVC projects includes an {id} segment. Removing that segment from your default route will make your existing code produce a query string.

Change this:

routes.MapRoute(
    "Default",                                              // Route name
    "{controller}/{action}/{id}",                           // URL with parameters
    new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
    );

To this:

routes.MapRoute(
    "Default",                                     // Route name
    "{controller}/{action}",                       // URL with parameters
    new { controller = "Home", action = "Index" }  // Parameter defaults
    );

Since the default (fallback) route that Asp.Net registers is including an {id} parameter in the url pattern:

// Default
routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

Your generated url adheres to this fallback pattern ({controller}/{action}/{id}) and appends your id using /{id}.

You'll need to register a custom route before the default route to exclude the {id}: 

routes.MapRoute(
    name: "Count",
    url: "Home/Count",
    defaults: new { controller = "Home", action = "Count" }
);

You can also try to remove the {id} from the default pattern (if it won't affect other actions) or change your id parameter in the Count action to a different name.

remove {id} from default config

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { 
            controller = "Home", 
            action = "Index", 
            id = UrlParameter.Optional }
    );
}

TO

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}",
        defaults: new { 
            controller = "Home", 
            action = "Index" }
    );
}
