MVC 5 ASPNET IDENTITY 不支持每种类型的多个对象集。但是我在整个项目中只有一个 DbSet

Question

我正在尝试登录网络应用程序。该数据库已经存在，所以我使用说明 here 自定义 table 以执行登录。我设法修复了一两个错误（？），现在我陷入了困境，我真的无法理解它从何而来。我的上下文是这样

public class ApplicationDbContext : IdentityDbContext<TblAdmin>
{
    public ApplicationDbContext()
        : base("TelecomConnection", throwIfV1Schema: false)
    {
        Database.SetInitializer<ApplicationDbContext>(null);
    }
    public DbSet<TblAdmin> TblAdmins { get; set; }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<TblAdmin>().ToTable("tblAdmins");
    }
}

最相关的问题是 this，这对我没有帮助。问题发生的时间点是当用户提供登录凭据时，编译器在这一行停止

 var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe,shouldLockout:false);

存在 this 的整个方法是这样的：

 public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        // This doesn't count login failures towards account lockout
        // To enable password failures to trigger account lockout, change to shouldLockout: true

        var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe,shouldLockout:false);
        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToLocal(returnUrl);
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            case SignInStatus.Failure:
                ModelState.AddModelError("", "Wrong Password.");
                return View(model);
            default:
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
        }
    }

我尝试并搜索了整个项目，甚至找不到整个世界 "Users"。谁能告诉我如何解决这个问题？

Answer 1

IdentityDbContext<TUser> 已经为 TUser 实现了 DbSet:

public IDbSet<TUser> Users { get; set; }

因为这里的TUser是TblAdmin(IdentityDbContext<TblAdmin>)，当你添加以下内容时：

public DbSet<TblAdmin> TblAdmins { get; set; }

TblAdmin 现在由 two DbSets.

Multiple object sets per type are not supported on MVC 5 ASPNET IDENTITY. But i have only one DbSet existing in the whole project
