不能在實體'AspNetUsers'的架構''中使用表'AspNetUsers',因為它被用於另一個實體

asp.net-core asp.net-core-mvc asp.net-identity-3 entity-framework-core

我們正在嘗試通過擴展AspNetUsers將Identity 3添加到我們現有的客戶應用程序中

    public class ApplicationUser : IdentityUser
{
    public string BusinessName { get; set; }
    public string ContactName { get; set; }
    public string CountryCode { get; set; }
    public virtual Countries Country { get; set; }
    public string AddressLabel { get; set; }
    public string Phone { get; set; }
    public DateTime? FollowUp { get; set; }
    public bool MailingList { get; set; }
    public int SubscriptionId { get; set; }
    [ForeignKey("SubscriptionId")]
    public virtual Subscriptions Subscription { get; set; }
    public virtual ICollection<Devices> Devices { get; set; }
    public virtual ICollection<Downloads> Downloads { get; set; }
    public virtual ICollection<Invoices> Invoices { get; set; }
    public virtual ICollection<Notes> Notes { get; set; }
    public virtual ICollection<Referrals> Referrals { get; set; }
}

CustomersContext繼承自IdentityDbContext

    public class ApplicationUser : IdentityUser
{
    public string BusinessName { get; set; }
    public string ContactName { get; set; }
    public string CountryCode { get; set; }
    public virtual Countries Country { get; set; }
    public string AddressLabel { get; set; }
    public string Phone { get; set; }
    public DateTime? FollowUp { get; set; }
    public bool MailingList { get; set; }
    public int SubscriptionId { get; set; }
    [ForeignKey("SubscriptionId")]
    public virtual Subscriptions Subscription { get; set; }
    public virtual ICollection<Devices> Devices { get; set; }
    public virtual ICollection<Downloads> Downloads { get; set; }
    public virtual ICollection<Invoices> Invoices { get; set; }
    public virtual ICollection<Notes> Notes { get; set; }
    public virtual ICollection<Referrals> Referrals { get; set; }
}

我們正在嘗試使用Microsoft身份驗證。當我運行應用程序並使用Microsoft帳戶登錄時,該應用程序在此行上的AccountController ExternalLoginCallback爆炸

    public class ApplicationUser : IdentityUser
{
    public string BusinessName { get; set; }
    public string ContactName { get; set; }
    public string CountryCode { get; set; }
    public virtual Countries Country { get; set; }
    public string AddressLabel { get; set; }
    public string Phone { get; set; }
    public DateTime? FollowUp { get; set; }
    public bool MailingList { get; set; }
    public int SubscriptionId { get; set; }
    [ForeignKey("SubscriptionId")]
    public virtual Subscriptions Subscription { get; set; }
    public virtual ICollection<Devices> Devices { get; set; }
    public virtual ICollection<Downloads> Downloads { get; set; }
    public virtual ICollection<Invoices> Invoices { get; set; }
    public virtual ICollection<Notes> Notes { get; set; }
    public virtual ICollection<Referrals> Referrals { get; set; }
}

錯誤是

    public class ApplicationUser : IdentityUser
{
    public string BusinessName { get; set; }
    public string ContactName { get; set; }
    public string CountryCode { get; set; }
    public virtual Countries Country { get; set; }
    public string AddressLabel { get; set; }
    public string Phone { get; set; }
    public DateTime? FollowUp { get; set; }
    public bool MailingList { get; set; }
    public int SubscriptionId { get; set; }
    [ForeignKey("SubscriptionId")]
    public virtual Subscriptions Subscription { get; set; }
    public virtual ICollection<Devices> Devices { get; set; }
    public virtual ICollection<Downloads> Downloads { get; set; }
    public virtual ICollection<Invoices> Invoices { get; set; }
    public virtual ICollection<Notes> Notes { get; set; }
    public virtual ICollection<Referrals> Referrals { get; set; }
}

除CustomersContext之外,沒有其他dbContext。我找不到任何映射到除ApplicationUser之外的AspNetUsers的實體。

沒有遷移。如果我嘗試創建初始遷移,也會發生同樣的錯誤。

    public class ApplicationUser : IdentityUser
{
    public string BusinessName { get; set; }
    public string ContactName { get; set; }
    public string CountryCode { get; set; }
    public virtual Countries Country { get; set; }
    public string AddressLabel { get; set; }
    public string Phone { get; set; }
    public DateTime? FollowUp { get; set; }
    public bool MailingList { get; set; }
    public int SubscriptionId { get; set; }
    [ForeignKey("SubscriptionId")]
    public virtual Subscriptions Subscription { get; set; }
    public virtual ICollection<Devices> Devices { get; set; }
    public virtual ICollection<Downloads> Downloads { get; set; }
    public virtual ICollection<Invoices> Invoices { get; set; }
    public virtual ICollection<Notes> Notes { get; set; }
    public virtual ICollection<Referrals> Referrals { get; set; }
}

對包含的代碼量表示歉意,但不包括那些關鍵信息。

一般承認的答案

當您從IdentityDbContext繼承時,您不需要重新創建AspNet* DbSet,只需添加新表即可。
您的CustomersContext應如下所示:

public partial class CustomersContext : IdentityDbContext<ApplicationUser>
{
    protected override void OnConfiguring(DbContextOptionsBuilder options)
    {
        options.UseSqlServer(@"Server=(localdb)\\mssqllocaldb;Database=Customers;Trusted_Connection=True;MultipleActiveResultSets=true");
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);// we have to do this because we are inheriting from IdentityDbContext<ApplicationUser> not DbContext

        // override the users tables with your properties
        modelBuilder.Entity<ApplicationUser>(entity =>
        {
            entity.HasIndex(e => e.BusinessName).HasName("BusinessNameIndex");

    public virtual DbSet<Invoices> Invoices { get; set; }
    public virtual DbSet<Notes> Notes { get; set; }
    public virtual DbSet<ReferralSources> ReferralSources { get; set; }
    public virtual DbSet<Referrals> Referrals { get; set; }
    public virtual DbSet<Subscriptions> Subscriptions { get; set; }
}

或者你可以在不調用base.OnModelCreating情況下完全創建模型,你可以從源代碼中復制OnModelCreating
