'/'应用程序中的asp.net mvc 5服务器错误

Question

我现在想用asp.net mvc 5和实体框架创建示例项目时，当我想运行该项目时，遇到以下错误：

在我的计算机上安装了.net 4.5和4.5.1，我的iis版本也是8。

这是我的控制器：

    using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using mvcWebApp01.Models;

namespace mvcWebApp01.Controllers
{
    public class HomeControllers : Controller
    {
        private DataBaseContext db = new DataBaseContext();

        // GET: HomeControllers
        public ActionResult Index()
        {
            return View(db.People.ToList());
        }

        // GET: HomeControllers/Details/5
        public ActionResult Details(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Person person = db.People.Find(id);
            if (person == null)
            {
                return HttpNotFound();
            }
            return View(person);
        }

        // GET: HomeControllers/Create
        public ActionResult Create()
        {
            return View();
        }

                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(person);
        }

        // GET: HomeControllers/Edit/5
        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Person person = db.People.Find(id);
            if (person == null)
            {
                return HttpNotFound();
            }
            return View(person);

        {

            {
                db.Entry(person).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(person);
        }

        // GET: HomeControllers/Delete/5
        public ActionResult Delete(int? id)
        {
            if (id == null)

            db.People.Remove(person);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                db.Dispose();
            }
            base.Dispose(disposing);
        }
    }
}

ASP.NET遵循“约定之上的配置”方法。 这意味着，例如，为了实例化您的控制器，默认的控制器工厂将尝试遵循命名约定<Name>Controller 。 如果您不喜欢这种方法，则可以编写自己的Controller Factory（例如，请参见此处 ），但是一般来说这不是必需的。

因此，要解决您的问题，您应该将HomeControllers重命名为HomeController 。
