自定义ASP.NET核心身份实体

Question

我正在自定义ASP.NET Core Identity的实体，但我在运行时遇到了这个错误：

Unhandled Exception: System.ArgumentException: GenericArguments[0], 
'Kento.Models.ApplicationUser', on 'Microsoft.AspNetCore.Identity
.EntityFrameworkCore.UserStore`4[TUser,TRole,TContext,TKey]' violates
the constraint of type 'TUser'. ---> System.TypeLoadException: Generic 
Arguments[0], 'Kento.Models.ApplicationUser', on 'Microsoft.AspNetCore
.Identity.EntityFrameworkCore.UserStore`9[TUser,TRole,TContext,TKey,
TUserClaim,TUserRole,TUserLogin,TUserToken,TRoleClaim]' violates the
constraint of type parameter 'TUser'.

以下是自定义实体列表：

的DbContext：

public class ApplicationDbContext : IdentityDbContext
    <ApplicationUser, 
    ApplicationRole, 
    string, 
    ApplicationUserClaim, 
    ApplicationUserRole, 
    ApplicationUserLogin, 
    ApplicationRoleClaim, 
    ApplicationUserToken>

ApplicationUser：

public class ApplicationUser : IdentityUser
     <string, ApplicationUserClaim, ApplicationUserRole, ApplicationUserLogin>

ApplicationRole：

public class ApplicationRole : IdentityRole
    <string, ApplicationUserRole, ApplicationRoleClaim>

ApplicationUserClaim：

public class ApplicationUserClaim : IdentityUserClaim<string>

ApplicationUserLogin

public class ApplicationUserLogin : IdentityUserLogin<string>

ApplicationRoleClaim

public class ApplicationRoleClaim : IdentityRoleClaim<string>

ApplicationUserToken

public class ApplicationUserToken : IdentityUserToken<string>

我很困惑这里发生了什么。
