无法访问我的索引

我正在使用c#和SQL Server 2005开发一个asp.net MVC 3应用程序。

我已经创建了2个模型(User &Poste和它们的控制器(UserController &PosteController)由于使用实体框架创建"读/写操作和视图"的方法。

一切顺利的Poste，我可以创建，编辑，删除…

问题与User有关。事实上，当我把/User放在我的URL访问索引，这个错误出现在我:

描述:在执行过程中发生未处理的异常当前的web请求。请查看堆栈跟踪了解更多信息有关错误及其在代码中的起源的信息。

异常详细信息:System.Data.SqlClient.SqlException: Nom d' objectdbo。用户无效

这是User模型代码:

    public class User
    {
        [Required]
        [Key]
        [Display(Name = "Matricule :")]
        public string Matricule { get; set; }
        [Required]
        [Display(Name = "Nom :")]
        public string Nom_User { get; set; }
        [Required]
        [StringLength(100, ErrorMessage = "Le {0} doit avoir au minimum {2} caractères.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Mot de passe :")]
        public string passWord { get; set; }
        [Required]
        [Display(Name = "Type :")]
        public string Type_User { get; set; }
        [Required]
        [Display(Name = "ID_UF :")]
        public string ID_UF { get; set; }
    }
    public class GammeDBContext : DbContext
    {
        public DbSet<User> Users { get; set; }
    }

，这是UserController代码:

    public class UserController : Controller
    {
        private GammeDBContext db = new GammeDBContext();
        //
        // GET: /User/
        public ViewResult Index()
        {
            return View(db.Users.ToList());
        }
        //
        // GET: /User/Details/5
        public ViewResult Details(string id)
        {
            User user = db.Users.Find(id);
            return View(user);
        }
        //
        // GET: /User/Create
        public ActionResult Create()
        {
            return View();
        } 
        //
        // POST: /User/Create
        [HttpPost]
        public ActionResult Create(User user)
        {
            if (ModelState.IsValid)
            {
                db.Users.Add(user);
                db.SaveChanges();
                return RedirectToAction("Index");  
            }
            return View(user);
        }
        //
        // GET: /User/Edit/5
        public ActionResult Edit(string id)
        {
            User user = db.Users.Find(id);
            return View(user);
        }
        //
        // POST: /User/Edit/5
        [HttpPost]
        public ActionResult Edit(User user)
        {
            if (ModelState.IsValid)
            {
                db.Entry(user).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(user);
        }
        //
        // GET: /User/Delete/5
        public ActionResult Delete(string id)
        {
            User user = db.Users.Find(id);
            return View(user);
        }
        //
        // POST: /User/Delete/5
        [HttpPost, ActionName("Delete")]
        public ActionResult DeleteConfirmed(string id)
        {            
            User user = db.Users.Find(id);
            db.Users.Remove(user);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        protected override void Dispose(bool disposing)
        {
            db.Dispose();
            base.Dispose(disposing);
        }
    }

，这是我在web.config文件中添加的内容:

<add name="GammeDBContext" 
     connectionString="Data Source=SWEET-DE396641E'SQLEXPRESS;database=Flux; Integrated Security=true" 
     providerName="System.Data.SqlClient" />
<add name="GammeDBContextP" 
     connectionString="Data Source=SWEET-DE396641E'SQLEXPRESS;database=Flux; Integrated Security=true" 
     providerName="System.Data.SqlClient" />

PS:

• GammeDBContext是为"用户"
• GammeDBContextP为"post"

有解决办法吗?

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<System.Data.Entity.ModelConfiguration.Conventions.PluralizingTableNameConvention>();
    }
