Web-API-Dienst HTTP-Statuscode 405 bei Methode POST

Question

GET funktioniert einwandfrei. Aber in Chrome mit POST-Methode habe ich: Fehler beim Laden der Ressource: Der Server antwortete mit einem Status von 405 (Method Not Allowed). Fehler beim Laden http://localhost:49834/api/Rest/: Antwort für Preflight hat ungültigen HTTP-Statuscode 405. In InterntExplorer habe ich: SCRIPT7002: XMLHttpRequest: Netzwerkfehler 0x80070005, Zugriff verweigert.

Controller:

[EnableCors("*", "*", "*")] 
    public class RestController : ApiController 
    { 
// POST: api/Rest 
     [HttpPost] 
     public void Post([FromBody]Request Request) 
     { 
      if (ModelState.IsValid) 
      { 
       db.Requests.Add(Request); 
       db.SaveChanges(); 
      } 
     } 
} 

WebApiConfig.cs

config.Routes.MapHttpRoute(
       name: "DefaultApi", 
       routeTemplate: "api/{controller}/{id}", 
       defaults: new { id = RouteParameter.Optional } 
      ); 
      var json = config.Formatters.JsonFormatter; 
      json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects; 
      config.Formatters.Remove(config.Formatters.XmlFormatter);

AJAX POST:

var url = "http://localhost:49834/"; 
$.ajax({ 
       type: "POST", 
       url: url + "api/Rest/", 
       contentType: "application/json; charset=utf-8", 
       dataType: "json", 
       data: JSON.stringify(submitData), 
       success: function (data) { 
       }, 
       error: function (err) { 
        console.log(err); 
        alert(err.status + " - " + err.statusText); 
       } 
      }) 

Ich benutze IIS Express: applicationHost.config Datei in% userprofile% \ Dokumente \ IISExpress \ config Ordner => ExtensionlessUrl-Integrated-4.0 Handler ist wie folgt konfiguriert Verb = "GET, HEAD, POST, DEBUG, PUT, DELETE"

GET funktioniert:

$.getJSON(url + "api/Rest").done(function (data) { 
        var mass = new Array();     
        $(data).each(function (index, e) { 
         ReqArray.push(e); 
        }) 
        vm.requests(ReqArray); 
       });

var url = "http://localhost:49834/";

         success: function (data) { 
         }, 
         error: function (err) { 
          console.log(err);
