无法创建AplicationRoleManager和ApplicationUserManager类（标识）

Question

当我在数据访问层中为ApplicationUserManager和ApplicationRoleManager类创建构造函数时，出现此错误：

There is no argument given that corresponds to the required formal parameter 'optionsAccessor' 
of 'UserManager<IdentityUser>.UserManager(IUserStore<IdentityUser>, IOptions<IdentityOptions>, 
IPasswordHasher<IdentityUser>, IEnumerable<IUserValidator<IdentityUser>>, 
IEnumerable<IPasswordValidator<IdentityUser>>, ILookupNormalizer, IdentityErrorDescriber, 
IServiceProvider, ILogger<UserManager<IdentityUser>>)'

There is no argument given that corresponds to the required formal parameter 'roleValidators'
 of 'RoleManager<IdentityRole>.RoleManager(IRoleStore<IdentityRole>, IEnumerable<IRoleValidator<IdentityRole>>, 
ILookupNormalizer, IdentityErrorDescriber, ILogger<RoleManager<IdentityRole>>)'

我的ApplicationRole类

    public class ApplicationRole : IdentityRole
    {

    }

我的User类

    public class User : IdentityUser
    {

    }

我的ApplicationRoleManager类

    public class ApplicationRoleManager : RoleManager<ApplicationRole>
    {
        public ApplicationRoleManager(RoleStore<ApplicationRole> store)
                    : base(store)// error here
        {

        }
    }

我的ApplicationUserManager类

    public class ApplicationUserManager : UserManager<User>
    {
        public ApplicationUserManager(IUserStore<User> store)
                : base(store) // error here
        {
        }
    }

（使用ASP.NET Core和AspNetCore.Identity）
