.NET Web API 2和IIS PUT / DELETE无法正常工作(.NET Web API 2 and IIS PUT/DELETE not working)

 在对我的Web API 2控制器的DELETE请求中，我得到： 
 
Request URL:http://localhost/phoenix/api/apps/1245 
Request Method:DELETE
Status Code:404 Not Found

DELETE http://localhost/myapp/api/apps/1245 404 (Not Found) 
 
 我的控制器看起来像： 
 
    [EnableCors(origins: "http://localhost", headers: "*", methods: "*", SupportsCredentials = true)]
[Route("api/apps")]
public class ApplicationController : ApiController
{
    // DELETE api/apps/5
    public void Delete(string id)
    {
        //apps.Delete(id);
    }
}
 
 我的IIS是为PUT / DELETE动词设置的： 
 
 
 我的web.config有* for verbs： 
 
<system.webServer>
  <handlers>
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <remove name="OPTIONSVerbHandler" />
  <remove name="TRACEVerbHandler" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
  </handlers>
</system.webServer>
 
 我错过了什么？ 

On DELETE requests to my Web API 2 controller, I get:
 
Request URL:http://localhost/phoenix/api/apps/1245 
Request Method:DELETE
Status Code:404 Not Found

DELETE http://localhost/myapp/api/apps/1245 404 (Not Found) 
 
my controller looks like:
 
    [EnableCors(origins: "http://localhost", headers: "*", methods: "*", SupportsCredentials = true)]
[Route("api/apps")]
public class ApplicationController : ApiController
{
    // DELETE api/apps/5
    public void Delete(string id)
    {
        //apps.Delete(id);
    }
}
 
and my IIS is setup for the PUT/DELETE verbs:
 
 
and my web.config has has * for verbs:
 
<system.webServer>
  <handlers>
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <remove name="OPTIONSVerbHandler" />
  <remove name="TRACEVerbHandler" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
  </handlers>
</system.webServer>
 
What am I missing?
