asp.net-mvc – IIS 7与IIS Express的路由错误,生成HTTP 404错误

当我在我的开发系统上切换到使用完整的IIS 7.5服务器时,我突然开始为我的两个控制器中的操作获取HTTP 404错误.其他控制器正常运行.这是从Visual Studio运行应用程序或直接从IIS运行.

我看不到任何配置差异.

其中一个表现出这种行为的控制器是：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Configuration;
using Mbrrace.ApplicationServices.Validation;

namespace Mbrrace.WebUI.Areas.Validation.Controllers
{
    public class ValidationController : Controller
    {
        //
        // GET: /Validation/Validation/

        [HttpGet]
        public JsonResult PostcodeCheck([Bind(Prefix = "perinatalView")]AddressViewModel model)
        {

            //  postcode has already been checked for correct format
            //  now look it up to see if it exists

            if (PostcodeChecks.CheckPostcodeExists(ConfigurationManager.ConnectionStrings["CommonCodeEntities"].ConnectionString,model.Postcode))
            {
                return Json(true,JsonRequestBehavior.AllowGet);
            }

            return Json("This postcode was not found in the database",JsonRequestBehavior.AllowGet);

        }

        [HttpPost]
        public JsonResult PostcodeExtendedCheck(String Postcode)
        {

            // check if it exists or of it's sector exists (all but last two characters

            string message = PostcodeChecks.PostcodeExtendedCheck(ConfigurationManager.ConnectionStrings["MbrraceCommonCodeEntities"].ConnectionString,Postcode,Postcode.Substring(0,Postcode.Length - 2));
            string success = (message.Length == 0) ? "OK" : "NO";
            var result = new { Success = success,Message = message };

            return Json(result,JsonRequestBehavior.AllowGet);
        }

        public class AddressViewModel
        {
            public string Postcode { get; set; }
        }

    }
}

这在IIS Express中的预期行为和部署到IIS的行为.当IIS连接到项目进行调试时,它会引发404错误.

任何人都可以详细说明为什么会产生404错误？
