Asp.Net Core 3.1 Identity LinqToDB.Identity UserStore 问题

Question

我一直在尝试为我的 .Net Core 3.1 项目实施 .Net Identity。在我的项目中，我使用 LinqToDB 来使用数据库。如，MySQL、MSSQL。我已经实现了我的身份类，如 AppUser、AppRole、AppUserClaim，并使用 LinqToDB 将它们创建到我的 mssql 数据库中。问题是，当项目运行时，它会返回一个这样的错误。

GenericArguments1, 'DevPlatform.Core.Domain.Identity.AppUser', on 'LinqToDB.Identity.UserStore`7[TKey,TUser,TRole,TUserClaim,TUserRole,TUserLogin,TUserToken]' 违反了类型的约束'TUser'。'

TypeLoadException: GenericArguments1, 'DevPlatform.Core.Domain.Identity.AppUser', on 'LinqToDB.Identity.UserStore`7[TKey,TUser,TRole,TUserClaim,TUserRole,TUserLogin,TUserToken]' 违反了约束类型参数“TUser”。

我在该代码块中收到此错误；

 public static void AddDevPlatformAuthentication(this IServiceCollection services, IConfiguration configuration)
    {
        services.AddIdentity<AppUser, LinqToDB.Identity.IdentityRole>(options =>
        {
            options.Password.RequireDigit = true;
            options.Password.RequiredLength = 4;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireUppercase = true;
            options.Password.RequireLowercase = false;

            options.User.RequireUniqueEmail = true;

            //TODO
            //options.User.RequireUniqueEmail = true; 
            //options.SignIn.RequireConfirmedEmail = true;
            //options.Lockout.MaxFailedAccessAttempts = 5;
            //options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(3);

        }).AddLinqToDBStores(new DefaultConnectionFactory())
            .AddDefaultTokenProviders();

        services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();

        // Uncomment the following lines to enable logging in with third party login providers

        JwtTokenDefinitions.LoadFromConfiguration(configuration);
        services.ConfigureJwtAuthentication();
        services.ConfigureJwtAuthorization();
    }

这是我继承自 IdentityUser 类的 AppUser 类。

using DevPlatform.Core.Entities;
using LinqToDB.Identity;
using System;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;

namespace DevPlatform.Core.Domain.Identity
{

public class AppUser : IdentityUser<int>, IEntity
{
    public DateTime CreatedDate { get; set; }
    public DateTime? ModifiedDate { get; set; }

    public int? CreatedBy { get; set; }
    public int? ModifiedBy { get; set; }
    public int? StatusId { get; set; }

    [Required]
    [ForeignKey("UserDetail")]
    public int DetailId { get; set; }

    public virtual AppUserDetail UserDetail { get; set; }
}
}

代码块太多了，这里就不贴了。如果有人可以提供帮助，我将非常高兴。

这个问题已经通过编辑 AddLinqToDBStores 解决了。

 public static void AddDevPlatformAuthentication(this IServiceCollection services, IConfiguration configuration)
    {
        services.AddIdentity<AppUser, LinqToDB.Identity.IdentityRole<int>>(options =>
        {
            options.Password.RequireDigit = true;
            options.Password.RequiredLength = 4;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireUppercase = true;
            options.Password.RequireLowercase = false;

            options.User.RequireUniqueEmail = true;

            //TODO
            //options.User.RequireUniqueEmail = true; 
            //options.SignIn.RequireConfirmedEmail = true;
            //options.Lockout.MaxFailedAccessAttempts = 5;
            //options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(3);

        }).AddLinqToDBStores<int, AppUserClaim, AppUserRole, AppUserLogin, AppUserToken, AppRoleClaim>(new
        IdentityConnectionFactory(new SqlServerDataProvider(ProviderName.SqlServer, SqlServerVersion.v2017), "SqlServerIdentity", DataSettingsManager.LoadSettings().ConnectionString))
            .AddDefaultTokenProviders();

        services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();

        // Uncomment the following lines to enable logging in with third party login providers

        JwtTokenDefinitions.LoadFromConfiguration(configuration);
        services.ConfigureJwtAuthentication();
        services.ConfigureJwtAuthorization();
    }
