аутентификация ядра asp.net с IdentityDbContext <AppUser, AppRole, int, AppUserClaim, AppUserRole, AppUserLogin, AppRoleClaim, AppUserToken>

Question

Я пытаюсь создать базу данных из первой модели кода. Когда я бегу dotnet ef migrations add или отладки приложения я получаю сообщение об ошибке:

TypeLoadException: GenericArguments[0], 'OpPISWeb.Models.AppUser', on 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore`9[TUser,TRole,TContext,TKey,TUserClaim,TUserRole,TUserLogin,TUserToken,TRoleClaim]' violates the constraint of type parameter 'TUser'. 
System.RuntimeTypeHandle.Instantiate(RuntimeTypeHandle handle, IntPtr* pInst, int numGenericArgs, ObjectHandleOnStack type) 

в коде:

.AddEntityFrameworkStores<AppWebContext, int>() 

Мой код в ConfigureServices является:

 var res = services 
      .AddIdentity<AppUser, AppRole>(config => 
      { 
       config.User.RequireUniqueEmail = true; 
       config.Password.RequireNonAlphanumeric = false; 
       config.Cookies.ApplicationCookie.AutomaticChallenge = false; 
      }) 
     .AddEntityFrameworkStores<AppWebContext, int>() 
     .AddDefaultTokenProviders(); 

и мои модели EF являются:

[Table("Roles")] 
public partial class AppRole : IdentityRole<int, AppUserRole, AppRoleClaim> 
{ 
} 
[Table("RoleClaims")] 
public partial class AppRoleClaim : IdentityRoleClaim<int> 
{ 
} 
[Table("Users")] 
public partial class AppUser : IdentityUser<int, AppUserClaim, AppUserRole, AppUserLogin> 
{ 
} 

//same for UserClaim, UserLogin, UserRole, UserToken 

и мой DBC-текст:

public partial class AppWebContext : IdentityDbContext<AppUser, AppRole, int, AppUserClaim, AppUserRole, AppUserLogin, AppRoleClaim, AppUserToken> 
{ 

    public AppWebContext() : base() { 
    } 

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) 
    { 
     optionsBuilder.UseSqlServer(@"Server=..."); 
    } 

    protected override void OnModelCreating(ModelBuilder modelBuilder) 
    { 
     base.OnModelCreating(modelBuilder); 

     modelBuilder.Entity<AppUser>(entity => 
     { 
      entity 
      .HasKey(u => u.Id); 
      entity.Property(p => p.Id) 
      .ValueGeneratedOnAdd(); 
     }); 

     modelBuilder.Entity<AppRole>(entity => 
     { 
      entity 
      .HasKey(u => u.Id); 
      entity.Property(p => p.Id) 
      .ValueGeneratedOnAdd(); 
     }); 

     modelBuilder.Entity<AppUserClaim>(entity => 
     { 
      entity 
      .HasKey(u => u.Id); 
      entity.Property(p => p.Id) 
      .ValueGeneratedOnAdd(); 
     }); 

     modelBuilder.Entity<AppUserRole>(entity => 
     { 
      entity 
      .HasKey(u => new { u.RoleId, u.UserId }); 
     }); 

     modelBuilder.Entity<AppRoleClaim>(entity => 
     { 
      entity 
      .HasKey(u => u.Id); 
      entity.Property(p => p.Id) 
      .ValueGeneratedOnAdd(); 
     }); 
    } 
} 

Что я пропустил? Я новичок в ASP.net и ASP.NET Core.
Я использую версию 1.1.

Полная ошибка:

An error occurred while starting the application.

Answer 1

When you are customizing ASP.NET Core Identity, you should not use AddEntityFrameworkStores anymore. Because it will override all of your previous settings and customization to default Identity services.

Answer 2

Ваша проблема вызвана .AddEntityFrameworkStores<AppWebContext, int>(). Взгляните на ответы HaoK в конце этого сообщения: https://github.com/aspnet/Identity/issues/1001.

Специально эти 2

"AddEntityFrameworkStores can only be called with a user that derives from IdentityUser. If you are specifying more generic arguments, use IdentityBuilder.AddUserStore() instead."

"AddEntityFrameworkStores can only be called with a role that derives from IdentityRole. If you are specifying more generic arguments, use IdentityBuilder.AddRoleStore() instead."

Так что, если вы хотите, чтобы переопределить UserClaimUserLogin, и все остальные, вам нужно реализовать свой собственный UserStore и RoleStore, а также использовать AddUserStore<T>() и AddRoleStore<T>() вместо AddEntityFrameworkStores.

AppUserStore

public class AppUserStore : UserStore<AppUser, AppRole, AppDbContext, int, AppUserClaim, AppUserRole, AppUserLogin, AppUserToken, AppRoleClaim> 
{ 
    public AppUserStore(AppDbContext dbContext) 
     : base(dbContext) 
    { 
    } 

    protected override AppUserToken CreateUserToken(AppUser user, string loginProvider, string name, string value) 
    { 
     throw new NotImplementedException(); 
    } 

    protected override AppUserLogin CreateUserLogin(AppUser user, UserLoginInfo login) 
    { 
     throw new NotImplementedException(); 
    } 

    protected override AppUserRole CreateUserRole(AppUser user, AppRole role) 
    { 
     throw new NotImplementedException(); 
    } 

    protected override AppUserClaim CreateUserClaim(AppUser user, Claim claim) 
    { 
     throw new NotImplementedException(); 
    } 
} 

AppRoleStore

public class AppRoleStore : RoleStore<AppRole, AppDbContext, int, AppUserRole, AppRoleClaim> 
{ 
    public AppRoleStore(AppDbContext dbContext) 
     : base(dbContext) 
    { 
    } 

    protected override AppRoleClaim CreateRoleClaim(AppRole role, Claim claim) 
    { 
     throw new NotImplementedException(); 
    } 
} 

И в вашем Startup.cs:

services.AddIdentity<AppUser, AppRole>() 
    .AddUserStore<AppUserStore>() 
    .AddRoleStore<AppRoleStore>() 
    // Components that generate the confirm email and reset password tokens 
    .AddDefaultTokenProviders(); 

Теперь я думаю, что вам нужно, чтобы создать свою собственную версию от UserManager, RoleManager и SignInManager. Ниже я расскажу о новых кодах, после того как я все выясню.
