C# EF代码第一个现有数据库-IdentityUser表问题

我对自定义用户有问题。 我有一个名为Profiles的表，用于我的users表（它不允许我使用users，但这是另一个问题！），我创建了dbcontext，如下所示：

public partial class SkipstoneContext : IdentityDbContext<Profile>
{
    static SkipstoneContext()
    {
        Database.SetInitializer<SkipstoneContext>(null); // Existing data, do nothing
    }

    public SkipstoneContext()
        : base("DefaultConnection")
    {
    }

    // ...
    public DbSet<Company> Companies { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(model => model.UserId);
        modelBuilder.Entity<IdentityRole>().HasKey<string>(model => model.Id);
        modelBuilder.Entity<IdentityUserRole>().HasKey(model => new { model.RoleId, model.UserId });
        modelBuilder.Entity<UserSecret>().HasKey<string>(model => model.UserName);
    }
}

public partial class Profile : IdentityUser
{
    public Profile()
    {
        // ...
    }

    public string CompanyId { get; set; }        
    public string Title { get; set; }
    public string Forename { get; set; }
    public string Surname { get; set; }
    public string Email { get; set; }
    // ...

    public virtual Company Company { get; set; }
    // ...
}

public partial class SkipstoneContext : DbContext // : IdentityDbContext<Profile>
{
    static SkipstoneContext()
    {
        Database.SetInitializer<SkipstoneContext>(null); // Exsting database, do nothing
    }

    public SkipstoneContext()
        : base("DefaultConnection")
    {
    }

    // ...
    public DbSet<Company> Companies { get; set; }
    public DbSet<Profile> Profiles { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        // ...
        modelBuilder.Configurations.Add(new CompanyMap());
        modelBuilder.Configurations.Add(new ProfileMap());
        /// ...
        //modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(model => model.UserId);
        //modelBuilder.Entity<IdentityRole>().HasKey<string>(model => model.Id);
        //modelBuilder.Entity<IdentityUserRole>().HasKey(model => new { model.RoleId, model.UserId });
        //modelBuilder.Entity<UserSecret>().HasKey<string>(model => model.UserName);
    }
}

public class ProfileMap : EntityTypeConfiguration<Profile>
{
    public IdentityUserMap()
    {
        // Primary Key
        this.HasKey(t => t.Id);

        // Properties
        this.Property(t => t.Id)
            .IsRequired()
            .HasMaxLength(128);

        this.Property(t => t.CompanyId)
            .IsRequired()

}

当我运行我的项目时，我得到一个错误

无效的对象名称“dbo.IdentityUsers”

如果我将表重命名为IdentityUsers并再次运行该项目，则会出现一个错误

无效的对象名称“dbo.Profiles”

这就是令人困惑的地方。看起来EF正在为用户寻找两个表，而不仅仅是一个

谁能给我解释一下原因吗

为了解决这个问题，我从SkipstoneContext中删除了继承的IdentityDbContent，而只是从DbContext中继承。 新的上下文类如下所示：

public partial class SkipstoneContext : IdentityDbContext<Profile>
{
    static SkipstoneContext()
    {
        Database.SetInitializer<SkipstoneContext>(null); // Existing data, do nothing
    }

    public SkipstoneContext()
        : base("DefaultConnection")
    {
    }

    // ...
    public DbSet<Company> Companies { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(model => model.UserId);
        modelBuilder.Entity<IdentityRole>().HasKey<string>(model => model.Id);
        modelBuilder.Entity<IdentityUserRole>().HasKey(model => new { model.RoleId, model.UserId });
        modelBuilder.Entity<UserSecret>().HasKey<string>(model => model.UserName);
    }
}

public partial class Profile : IdentityUser
{
    public Profile()
    {
        // ...
    }

    public string CompanyId { get; set; }        
    public string Title { get; set; }
    public string Forename { get; set; }
    public string Surname { get; set; }
    public string Email { get; set; }

    public SkipstoneContext()
        : base("DefaultConnection")
    {

    // ...

它有一个IdentityUser属性，我认为这就是导致我的问题的原因。我知道Profile继承了IdentityUser，但出于某种原因，它似乎认为它在另一个表中

---

因此，我的下一个任务是创建一个自定义用户登录名，看看是否可以让EF使用IdentityUserLogin的替代名

好的，我解决了这个问题。这是由于我的映射。我的配置文件映射类如下所示：

public partial class SkipstoneContext : IdentityDbContext<Profile>
{
    static SkipstoneContext()
    {
        Database.SetInitializer<SkipstoneContext>(null); // Existing data, do nothing
    }

    public SkipstoneContext()

    {
    }

    // ...
    public DbSet<Company> Companies { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(model => model.UserId);
        modelBuilder.Entity<IdentityRole>().HasKey<string>(model => model.Id);
        modelBuilder.Entity<IdentityUserRole>().HasKey(model => new { model.RoleId, model.UserId });
        modelBuilder.Entity<UserSecret>().HasKey<string>(model => model.UserName);
    }
