如何在继承自IdentityDbContext的类中使用配置？

Question

最近，我想在我的C＃MVC Web应用程序中实现身份验证，因此我开始遵循Claim based authorization design for conditional edit operation in ASP.NET MVC App中的指南。但是，当涉及到我的DbContext类时，我遇到了一个问题。

如果没有出现多个错误，我似乎无法使其正常工作。如果我解决其中一个问题，另一个将中断。我尝试查找它，但似乎没有人遇到和我一样的问题。

我不明白为什么它会中断，因为从现在开始继承的类仍然从DbContext继承，它们之间只有2个类。

使用类实现DbContext的代码，此代码的工作需要更改

using Microsoft.EntityFrameworkCore;
using ProjectKiwi.Data.Mappers;
using ProjectKiwi.Models.Domain;

namespace ProjectKiwi.Data
{
    public class ApplicationDbContext : DbContext
    {
        public DbSet<Nieuwsartikel> Artikels { get; set; }
        public DbSet<Bestuurslid> Bestuurleden { get; set; }
        public DbSet<Locatie> Locaties { get; set; }
        public DbSet<ContactPagina> ContactPaginas { get; set; }
        public DbSet<Spreker> Sprekers { get; set; }
        public DbSet<Seminarie> Seminaries { get; set; }
        public DbSet<Categorie> Categories { get; set; }
        public DbSet<Deelnemer> Deelnemers { get; set; }
        public DbSet<Inschrijving> Inschrijvingen { get; set; }
        public DbSet<Organisatie> Organisaties { get; set; }
        public DbSet<Forumpost> Forumposts { get; set; }

        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder builder)
        { //I really need these configurations in my new app so I can choose how mapping is done.
            base.OnModelCreating(builder);
            builder.ApplyConfiguration(new ArtikelConfiguration());
            builder.ApplyConfiguration(new BestuurslidConfiguration());
            builder.ApplyConfiguration(new LocatieConfiguration());
            builder.ApplyConfiguration(new ContactPaginaConfiguration());
            builder.ApplyConfiguration(new CategorieConfiguration());
            builder.ApplyConfiguration(new DeelnemerConfiguration());
            builder.ApplyConfiguration(new InschrijvingConfiguration());
            builder.ApplyConfiguration(new OrganisatieConfiguration());
            builder.ApplyConfiguration(new SeminarieConfiguration());
        }
    }
}

带有实现IdentityDbContext的类的代码，此代码根本不起作用，只是显示了我要解决的问题

applyConfiguration似乎不起作用。我也不再有任何构造函数，而且我不知道我是否还需要任何构造函数。

using Microsoft.AspNet.Identity.EntityFramework;
using ProjectKiwi.Data.Mappers;
using ProjectKiwi.Models.Domain;
using System.Data.Entity;

namespace ProjectKiwi.Data
{
    public class ApplicationDbContext : IdentityDbContext
    {
        public DbSet<Nieuwsartikel> Artikels { get; set; }
        public DbSet<Bestuurslid> Bestuurleden { get; set; }
        public DbSet<Locatie> Locaties { get; set; }
        public DbSet<ContactPagina> ContactPaginas { get; set; }
        public DbSet<Spreker> Sprekers { get; set; }
        public DbSet<Seminarie> Seminaries { get; set; }
        public DbSet<Categorie> Categories { get; set; }
        public DbSet<Deelnemer> Deelnemers { get; set; }
        public DbSet<Inschrijving> Inschrijvingen { get; set; }
        public DbSet<Organisatie> Organisaties { get; set; }
        public DbSet<Forumpost> Forumposts { get; set; }

        protected override void OnModelCreating(DbModelBuilder builder)
        {
            base.OnModelCreating(builder);
            builder.ApplyConfiguration(new ArtikelConfiguration());
            builder.ApplyConfiguration(new BestuurslidConfiguration());
            builder.ApplyConfiguration(new LocatieConfiguration());
            builder.ApplyConfiguration(new ContactPaginaConfiguration());
            builder.ApplyConfiguration(new CategorieConfiguration());
            builder.ApplyConfiguration(new DeelnemerConfiguration());
            builder.ApplyConfiguration(new InschrijvingConfiguration());
            builder.ApplyConfiguration(new OrganisatieConfiguration());
            builder.ApplyConfiguration(new SeminarieConfiguration());
        }
    }
}

我希望能够使用我的配置来映射我的类并将该类用作我的DbContext。我需要DbSet来存储所有数据。
