'MyIdentityModels.User'が 'TUser'タイプの制約に違反しています

Question

ASP.NET IDコアをカスタマイズしようとしていて、次の例外が発生しています。（正常にビルドされているようですが、起動前にもクラッシュします）

Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: GenericArguments[0], 'Echap.Models.Models.Identity.User', on 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore`4[TUser,TRole,TContext,TKey]' violates the constraint of type 'TUser'. ---> System.TypeLoadException: GenericArguments[0], 'Echap.Models.Models.Identity.User', on 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore`9[TUser,TRole,TContext,TKey,TUserClaim,TUserRole,TUserLogin,TUserToken,TRoleClaim]' violates the constraint of type parameter 'TUser'.

私が知る限り、私はすべてのことを正しくやっています、なぜこれが起こっていますか？ここで

public sealed class ApplicationDbContext : IdentityDbContext<User, Role, int, UserClaim, UserRole, UserLogin, RoleClaim, UserToken> 
{ 
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options) 
    { 
     try 
     { 
      Database.EnsureCreated(); 
     } 
     catch (Exception e) 
     { 
     } 
    } 

    public DbSet<Category> Categories { get; set; } 
    public DbSet<CategoryService> CategoryServices { get; set; } 
    public DbSet<Coating> Coatings { get; set; } 
    public DbSet<Corner> Corners { get; set; } 
    public DbSet<Order> Orders { get; set; } 
    public DbSet<Press> Presses { get; set; } 
    public DbSet<PressData> PressDatas { get; set; } 
    public DbSet<PressService> PressServices { get; set; } 
    public DbSet<PrintedSide> PrintedSides { get; set; } 
    public DbSet<PrintSize> PrintSizes { get; set; } 
    public DbSet<Quantity> Quantities { get; set; } 
    public DbSet<Service> Services { get; set; } 
    public DbSet<ServiceCoating> ServiceCoatings { get; set; } 
    public DbSet<ServiceCorner> ServiceCorners { get; set; } 
    public DbSet<ServicePrintedSide> ServicePrintedSides { get; set; } 
    public DbSet<ServicePrintSize> ServicePrintSizes { get; set; } 
    public DbSet<ServiceQuantity> ServiceQuantities { get; set; } 


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


     modelBuilder.Entity<User>().ToTable("Users"); 
     modelBuilder.Entity<Role>().ToTable("Roles"); 
     modelBuilder.Entity<UserRole>().ToTable("UserClaims"); 
     modelBuilder.Entity<UserRole>().ToTable("UserRoles"); 
     modelBuilder.Entity<UserLogin>().ToTable("UserLogins"); 
     modelBuilder.Entity<RoleClaim>().ToTable("RoleClaims"); 
     modelBuilder.Entity<UserToken>().ToTable("UserToken"); 
    } 
} 

は私のUserクラスです：

public class User : IdentityUser<int, UserClaim, UserRole, UserLogin> 
{ 
    public User() 
    { 
     Presses = new List<Press>(); 
    } 

    public string TestField { get; set; } 

    public virtual ICollection<Press> Presses { get; set; } 
} 

、ここでは私の役割のクラスである：

public class Role : IdentityRole<int, UserRole, RoleClaim> {} 

は、これは私がStartup.csでアイデンティティを追加する方法です：

services.AddIdentity<User, Role>() 
       .AddEntityFrameworkStores<ApplicationDbContext, int>() 
       .AddDefaultTokenProviders();

次の変更を加えて問題を解決できました：

User.cs

public class User : IdentityUser<int> 

Role.cs

public class Role : IdentityRole<int> {} 

ApplicationDbContext：ApplicationDbContext内側また

public sealed class ApplicationDbContext : IdentityDbContext<User, Role, int> 

Iを添加：

modelBuilder.Entity<User>().ToTable("Users"); 
modelBuilder.Entity<Role>().ToTable("Roles"); 
modelBuilder.Entity<IdentityUserClaim<int>>().ToTable("UserClaims"); 
modelBuilder.Entity<IdentityUserRole<int>>().ToTable("UserRoles"); 
modelBuilder.Entity<IdentityUserLogin<int>>().ToTable("UserLogins"); 
modelBuilder.Entity<IdentityRoleClaim<int>>().ToTable("RoleClaims"); 
modelBuilder.Entity<IdentityUserToken<int>>().ToTable("UserToken");
