Why doesn't ASP.NET see the route through the route attribute?

Question

ASP.NET

In general, the project combines both asp.net mvc and asp.net webapi. The problem arises when using Areas and specifying routes for ApiControllers. Two identical classes in different areas (for example, TestController in Site and Manager area). Both have a RoutePrefix attribute. And no asp.net route wants to process. Not from the site area nor from the manager area.

namespace Test.Web.Areas.Site.Controllers {
    [RoutePrefix("api/test")]
    public class TestContoller : ApiController {
             [HttpGet]
             [Route("testone")]
             public IHttpActionResult TestOne() {
                   return Ok(new { test = "OK"});
             }
    }
}

namespace Test.Web.Areas.Manager.Controllers {
    [RoutePrefix("api/test")]
    public class TestContoller : ApiController {
             [HttpGet]
             [Route("testtwo")]
             public IHttpActionResult TestTwo() {
                   return Ok(new { test = "OK2"});
             }
    }
}

What am I doing wrong?

Answer 1

in RouteConfig wrote

// Enable attribute routing.
            routes.MapMvcAttributeRoutes();
