[HttpPost] 속성을 사용하더라도 컨트롤러 동작 모호성? (ASP.NET MVC4)

Question

그래서 내 서비스에 등록 할 사람들을위한 간단한 양식 인 "Register"보기 (RegisterController에 매핑 됨)가 있습니다. 폼의 메소드가 POST라는 것을 감안할 때, 컨트롤러의 액션 (폼을 보여주는 액션과 제출을받는 액션) 모두를 같은 이름으로 명명 할 수 있지만 [HttpPost] 속성을 통해 다음과 같이 구분합니다.

open System 
open System.Web 
open System.Web.Mvc 
open System.Net 
open System.Threading 
open System.Configuration 

[<HandleError>] 
type RegisterController() = 
    inherit Controller() 

    member this.Index (guid: string) = 
     let model = new RegisterModel(guid) 
     this.View("Register", model) :> ActionResult 

    [<HttpPost>] 
    member this.Index 
     (guid: string, password: string, passwordRetry: string) = 
      if not (password.Equals(passwordRetry)) then 
       raise(new Exception("Passwords must be the same")) 
      WebDbAccess.SetNewPassword guid password 
      RedirectResult("/") :> ActionResult 

이것은 완벽하게 작동합니다.

그러나이 기능을 내 앱의 홈보기 (로그인 기능 용)에서 사용하려고 시도했지만 작동하지 않습니다. 그것은 이것을 던졌습니다 :

2 가지 경우의 차이점은 무엇입니까? 나는 그것을 얻지 않는다.

HomeController의 구현은 다음과 같습니다

open System 
open System.Web 
open System.Web.Http 

[<HandleError>] 
type HomeController() = 
    inherit Controller() 

    [<HttpGet>] 
    member this.Index() = 
     this.View() :> ActionResult 

    [<HttpPost>] 
    member this.Index 
     (id:string, password:string) = 
      if (UserIsValid id password) then 
       RedirectResult("lobby") :> ActionResult 
      RedirectResult("loginError") :> ActionResult

@nemesv 잘했다, 나는 그렇지 않으면 System.Web.Http.HttpPost을 사용하기 때문에 완전히 System.Web.Mvc.HttpPost와 HttpPost을 한정했다!
