Why Is My Request Going to the Wrong Route?

Question

My request is working, but it is not going to the right route. I don't understand why.

I am receiving my '200 ok' response when I start the project but it is at the wrong route.

I want the route http://localhost:4047/api/[controller] but instead http://localhost:4047/ is working! No where am I specifying this route.

Here is the controller.

[EnableCors(origins: "*", headers: "*", methods: "*")]
[Route("api/[controller]")]
public class MenuController : ApiController
{
    private IMenuRepo xMenuRepo;
    public MenuController(IMenuRepo iopt)
    {
        xMenuRepo = iopt;
    }
    [HttpGet]
    [Route("")]
    public HttpResponseMessage GetOk()
    {
        return new HttpResponseMessage(HttpStatusCode.OK);
    }
}

Here is the WebApiConfig

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services
    config.EnableCors();
    // Web API routes
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}"
    );
}

Here is the Route Config

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

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

As far as I can tell, api/Menu should be the correct route.

Yes you are specifying the route

//GET /
[HttpGet]
[Route("")]
public HttpResponseMessage GetOk()
{
    return new HttpResponseMessage(HttpStatusCode.OK);
}

The controller needs a route prefix, while example is only specifying a controller route.

Change to:

[EnableCors(origins: "*", headers: "*", methods: "*")]
[RoutePrefix("api/Menu")]
public class MenuController : ApiController {
    private IMenuRepo xMenuRepo;
    public MenuController(IMenuRepo iopt) {
        xMenuRepo = iopt;
    }

    //GET api/Menu
    [HttpGet]
    [Route("")]
    public HttpResponseMessage GetOk() {
        return new HttpResponseMessage(HttpStatusCode.OK);
    }
}

The syntax in the OP [Route("api/[controller]")] is for asp.net-core
