在Identity Asp.net core 3 MVC中创建服务IUserStore时出错

更新资料

请参阅下面的更新。

我最近问了一个先前的stackoverflow问题，但是在实现以下两个方面的建议解决方案后，在ASP.NET Core中的身份模型自定义和ASP.NET Core Identity的自定义存储提供程序中，我遇到了一个问题。我只是无法获得解决方案。我已IdentityUser按照建议实施的扩展和的扩展IdentityRole。我已经实现IUserPasswordStore，并IUserRoleStore与IUserStore对UserStore，我已经实现IRoleStore了RoleStore。我还实现了新的dbContext ApplicationDbContext，它实现了IdentityDbContext。由于构造函数不接受参数，因此出现了问题，因此我实现了一个新的构造函数。我不确定这是否正确。

但是，这似乎无关紧要，因为调用时我在Program.cs的Main方法中收到错误

CreateHostBuilder(args).Build().Run(); 

错误是巨大的。我把它放在最后。在线搜索错误的各个部分并没有提供有关我在做什么的任何想法，并且由于我是ASP.NET Core 3和Identity的新手，所以我很困惑。

这是我到目前为止的代码。

ConfigureServices方法

public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
        services.AddMvc(options =>
        {
            var policy = new AuthorizationPolicyBuilder().RequireAuthenticatedUser().Build();
            options.Filters.Add(new AuthorizeFilter(policy));
        options.EnableEndpointRouting = false;
        });

        services.AddDbContext<EntitiesModel>(options => options.UseSqlServer(
            Configuration["Data:ConnectionStrings:XXXXDbConnection"]));
        services.AddIdentity<UserViewModel,RoleViewModel>().AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders().AddRoles<RoleViewModel>(); ;
        services.AddTransient<IUserStore<UserViewModel>, UserStore>();
        services.AddTransient<IRoleStore<RoleViewModel>, RoleStore>();
        services.ConfigureApplicationCookie(options =>
        {
            options.LoginPath = "/Login";
            options.LogoutPath = "/Logout";
        });
    }

ApplicationDbContext-这些都在同一个命名空间中

public class IdentityDbContext
    : IdentityDbContext<IdentityUser, IdentityRole, string>
{
    public IdentityDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
    {
    }
}

public class IdentityDbContext<TUser>
    : IdentityDbContext<TUser, IdentityRole, string>
    where TUser : IdentityUser
{
    public IdentityDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
    {
    }
}

// Uses the built-in Identity types except with custom User and Role types
// The key type is defined by TKey
public class IdentityDbContext<TUser, TRole, TKey> : IdentityDbContext<
    TUser, TRole, TKey, IdentityUserClaim<TKey>, IdentityUserRole<TKey>,
    IdentityUserLogin<TKey>, IdentityRoleClaim<TKey>, IdentityUserToken<TKey>>
    where TUser : IdentityUser<TKey>
    where TRole : IdentityRole<TKey>
    where TKey : IEquatable<TKey>
{
    private DbContextOptions<ApplicationDbContext> options;
    //private string nameOrConnectionString;

    public IdentityDbContext(DbContextOptions<ApplicationDbContext> options)
    {
        this.options = options;
    }

}

public abstract class IdentityDbContext<
        TUser, TRole, TKey, TUserClaim, TUserRole, TUserLogin, TRoleClaim, TUserToken>
    : IdentityUserContext<TUser, TKey>
    where TUser : IdentityUser<TKey>
    where TRole : IdentityRole<TKey>
    where TKey : IEquatable<TKey>
    where TUserRole : IdentityUserRole<TKey>
{

}
public class ApplicationDbContext : IdentityDbContext<UserViewModel,RoleViewModel,int>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

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

        modelBuilder.Entity<UserViewModel>(b =>
        {               
            b.HasMany(e => e.UserRoles)
                .WithOne()
                .HasForeignKey(ur => ur.Id)
                .IsRequired();
        });
        modelBuilder.Entity<UserViewModel>(b =>
        {
            b.ToTable("T_CustomerContacts");
        });
        modelBuilder.Entity<RoleViewModel>(b =>
        {
            b.ToTable("T_LoginRoles");
        });
        modelBuilder.Entity<UserRoleViewModel>(b =>
        {
            b.ToTable("T_CustomerContactRole");
        });         
        modelBuilder.Entity<RoleViewModel>(b =>
        {
            b.HasMany(e => e.UserRoles)
                .WithOne(e => e.Role)
                .HasForeignKey(ur => ur.RoleId)
                .IsRequired();
        });
    }
}

UserViewModel

public class UserViewModel : IdentityUser<int>
{

UserRoleViewModel

public class UserRoleViewModel : IdentityUserRole<int>
{

角色视图模型

public class RoleViewModel : IdentityRole<int>
{   

角色商店

public class RoleStore : IRoleStore<RoleViewModel>
{

用户商店

public class UserStore : IUserStore<UserViewModel>, IUserPasswordStore<UserViewModel>, IUserRoleStore<UserRoleViewModel>
{

我必须补充，这是我尝试过的最终配置。我尝试了许多组合和解决方案。部分错误如下

启动应用程序时发生错误。AggregateException：无法构造某些服务（验证服务描述符'ServiceType：Microsoft.AspNetCore.Identity.IUserStore 1[TrussCorp.CustomerPortal.Models.ViewModel.Identity.UserViewModel] Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore4 [TrussCorp.CustomerPortal.Models.ViewModel.Identity.UserViewModel，TrussCorp.CustomerPortal.Models.ViewModel.Identity .RoleViewModel，TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext，System.Int32]'：尝试激活“ Microsoft.AspNetCore.Identity”时，无法解析类型为“ TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext”的服务.EntityFrameworkCore.UserStore 4[TrussCorp.CustomerPortal.Models.ViewModel.Identity.UserViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.RoleViewModel,TrussCorp.CustomerPortal.Models.ViewModel.Identity.ApplicationDbContext,System.Int32]'.)

更新资料

我回到了上一个问题的开头，但是通过反转以下命令的顺序解决了上述错误

    services.AddTransient<IUserStore<UserViewModel>, UserStore>();
        services.AddTransient<IRoleStore<RoleViewModel>, TrussCorp.CustomerPortal.Identity.RoleStore>();
        services.AddIdentity<UserViewModel,RoleViewModel>().AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders().AddRoles<RoleViewModel>();

但是，正如现在所说，我得到的Store没有实现IUserRoleStore UserManager.GetUserRoleStore（）错误，这使我回到了平方。
