Question

我的项目工作正常，但现在我尝试添加一个新的View，我收到错误：“运行所选代码生成器时出错，无法检索TravelAgencyMVC.Models.ViewModel.ToursPackageView'的元数据

我的模特：

    namespace TravelAgencyMVC.Models.ViewModel
{
    public class ToursPackageView
    {
        [Key]
        public int ToursPackageID { get; set; }

        [Display(Name = "Title")]
        public string Title { get; set; }

        [Display(Name = "Description")]
        public string Description { get; set; }

        [Display(Name = "Image")]
        public string Image { get; set; }

        [Display(Name = "Price")]
        public decimal Price { get; set; }
    }
}

我的DbContext：

public partial class TravelAgencyDBEntities : DbContext
{

    public TravelAgencyDBEntities()
        : base("name=TravelAgencyDBEntities")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }

    public virtual DbSet<ToursPackage> ToursPackages { get; set; }
    public virtual DbSet<User> Users { get; set; }

    public System.Data.Entity.DbSet<TravelAgencyMVC.Models.ViewModel.UserSignUpView> UserSignUpViews { get; set; }

    public System.Data.Entity.DbSet<TravelAgencyMVC.Models.ViewModel.UserLoginView> UserLoginViews { get; set; }

    public System.Data.Entity.DbSet<TravelAgencyMVC.Models.ViewModel.ToursPackageView> ToursPackageViews { get; set; }
}

}

我已经检查了connectionStrings和提供者。他们看起来很好。有谁知道导致该错误的原因是什么？

由于

mvc脚手架viewmodel不工作
