与实体框架模型到表格约定

我有这个型号：

public class LkUpTitleModel
{
    [Key]
    public int TitleID { get; set; }
    [Required(AllowEmptyStrings = false, ErrorMessage = " * Has been left empty")]
    [DisplayName("Title")]
    [Remote("LkUpTitle", "Treeview", AdditionalFields = "TitleID", HttpMethod = "POST", ErrorMessage = " * Already exists")]
    public string Title { get; set; }
}

绑定到此db上下文

namespace MyWork.DAL
{
    public class DataBaseContext : DbContext
    {
        public DataBaseContext() : base("name = constring")
        {}

        public DbSet<LkUpGenderModel> vwLkUpGender { get; set; }
        public DbSet<LkUpTitleModel> vwLkUpTitle { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
            base.OnModelCreating(modelBuilder);
        }
    }
}

在控制器中：

public DataBaseContext db = new DataBaseContext();

这是远程验证功能中的类

[HttpPost]
public JsonResult LkUpTitle(string Title, int? TitleID)
{
    if (TitleID == null)
    {
        TitleID = 0;
    }

    var title = (from g in db.vwLkUpTitle where g.TitleID != TitleID select g).ToList();

    return Json(!title.Any(x => x.Title.ToUpper() == Title.ToUpper()));
}

当它运行并尝试验证时，我得到以下错误。不确定为什么要寻找dbo.LkUpTitleModel而不是dbo.vwLkUpTitle

  

＆＃39; /＆＃39;中的服务器错误应用

     

无效的对象名称＆＃39; dbo.LkUpTitleModel＆＃39;。
