Nilai tidak boleh nol. Nama parameter: nilai, CreateIdentityAsync?

Saya membuat ViewModel (UserModel) yang mengimplementasikan IUser<int> (untuk mengkustomisasi ASP.NET Identity 2.0)

public class UserModel : IUser<int>
{
    public int Id { get; set; }

    public string SecurityStamp { get; set; }

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

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

    public string FullName { get; set; }

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

    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [Display(Name = "E-Mail")]
    public string Email { get; set; }

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

    public List<Claim> Claims { get; set; }

    [IgnoreMapping]
    public List<CommentModel> Comments { get; set; }
}

Semuanya baik-baik saja, tetapi metode GenerateUserIdentityAsync.
Kode berikut ini adalah GenerateUserIdentityAsync saya di UserModel:

public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<UserModel, int> manager)
{
    this.SecurityStamp = Guid.NewGuid().ToString();
    this.Claims = new List<Claim>();

    ClaimsIdentity userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);//Exception : Value cannot be null. Parameter name: value

    return userIdentity;
}

Pengecualian telah terjadi dalam metode CreateIdentityAsync dengan jejak stack berikut

ArgumentNullException: Value cannot be null.

Bisakah Anda membimbing saya di mana kesalahan saya?

Saya menghadapi masalah yang sama saat meningkatkan dari ASP.NET Identity 1 ke ASP.NET Identity 2 dan saya menyelesaikannya dengan meletakkan string acak di bidang SecurityStamp.

Saya menemukan solusi ini di sini .

Saya harap ini bekerja untuk Anda juga.

Seperti yang disebutkan Sam dalam komentarnya untuk jawaban sebelumnya, solusi saya untuk masalah ini adalah memastikan bahwa pengguna yang saya buat dalam metode Seed dari Migrasi EF memiliki sesuatu dalam SecurityStamp. Setelah saya melakukan itu dan melakukan update-database -force, saya bisa masuk dengan baik.

context.Users.AddOrUpdate(u => u.UserName,
                new ApplicationUser
                {
                    UserName = "demo",
                    Email = "[email protected]",
                    EmailConfirmed = true,
                    PhoneNumberConfirmed = true,
                    PasswordHash = password,
                    PhoneNumber = "111-222-3344",
                    SecurityStamp = Guid.NewGuid().ToString() //THIS IS WHAT I NEEDED
                });

Jika Anda membuat pengguna Anda melalui beberapa cara lain, Anda harus dapat memperbaikinya dengan meletakkan string di kolom db pengguna melalui sql dan memiliki kesuksesan yang sama.

Dalam cara yang mirip dengan Kevin, kami juga mengalami masalah ini. Ternyata ketika seeding database seseorang lupa untuk mengatur properti UserName yang menghasilkan kesalahan yang sama.

Saya memiliki masalah yang lebih umum - beberapa klaim saya memiliki nilai Null di tabel AspNetUserClaims setelah rutin upgrade sql berjalan.

Saya memecahkan masalah dengan mengatur Nilai ClaimVile ke string kosong.
