Question

我现在有以下代码，使用EF 6：

public class ApplicationUser : IdentityUser
{
    public virtual ICollection<Client> Clients { get; set; }
}

    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext()
            : base("DefaultConnection")
        {
        }
    }

自定义：

public class MembershipManagerDbContext : DefaultDbContext
{
    public MembershipManagerDbContext()
    {
    }

    // db entities
    public DbSet<Student> Students { get; set; }
    public DbSet<Member> Members { get; set; }
    public DbSet<Payment> Payments { get; set; }
    public DbSet<PaymentType> PaymentTypes { get; set; }
    public DbSet<Address> Addresses { get; set; }
    public DbSet<Client> Client { get; set; }
    public DbSet<ClientPayment> ClientPayment { get; set; }
    //public DbSet<ClientUser> ClientUser { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        // moved migrations to Migrations folder
        modelBuilder.Configurations.Add(new StudentConfiguration());
        modelBuilder.Configurations.Add(new MemberConfiguration());
        modelBuilder.Configurations.Add(new AddressConfiguration());
        modelBuilder.Configurations.Add(new PaymentConfiguration());
        modelBuilder.Configurations.Add(new PaymentTypeConfiguration());
        modelBuilder.Configurations.Add(new ClientConfiguration());
        modelBuilder.Configurations.Add(new ClientPaymentConfiguration());
    }
}

Client.cs

public class Client: DbEntityWithId
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Website { get; set; }
    public string Telephone { get; set; }
    public string Mobile { get; set; }
    public DateTime LicenseStart { get; set; }
    public DateTime LicenseEnd { get; set; }

    public bool IsSuspended { get; set; } = false;
    public int MemberLicense { get; set; }
    public string AdditionalInfo { get; set; }

    public int AddressId { get; set; }
    public virtual Address Address { get; set; }

    public virtual ICollection<ClientPayment> ClientPayments { get; set; }
    public virtual ICollection<ApplicationUser> Users { get; set; }
}

FluentApi映射：

public class ClientConfiguration : EntityTypeConfiguration<Client>
{
    public ClientConfiguration()
    {
        // create FK
        HasRequired<Address>(s => s.Address)
                .WithMany(s => s.Clients);

        HasMany<ApplicationUser>(s => s.Users)
            .WithMany(c => c.Clients)
            .Map(cs =>
            {
                cs.MapLeftKey("ClientId");
                cs.MapRightKey("UserId");
                cs.ToTable("ClientUser");
            });
    }
}

在Package Manager中执行update-database命令时，出现以下错误：

MembershipManager.EntityFramework.Context.IdentityUserLogin :: EntityType'IdentityUserLogin'没有定义键。定义密钥这个EntityType。 MembershipManager.EntityFramework.Context.IdentityUserRole :: EntityType'IdentityUserRole'没有定义键。定义密钥这个EntityType。 IdentityUserLogins：EntityType：EntitySet 'IdentityUserLogins'基于没有的类型'IdentityUserLogin' 键定义。 IdentityUserRoles：EntityType：EntitySet 'IdentityUserRoles'基于没有的'IdentityUserRole'类型键定义。

您可能希望了解自定义IdentityDbContext的基础知识：https://codereview.stackexchange.com/questions/85741/identity-repository-pattern-with-unit-of-work/102087#102087

我认为这个主题相当困难，特别是如果您尝试在一个解决方案中使用多个项目。但使用IdentityDbContext会对你有所帮助！
