EF代碼首先與ASP.NET身份表建立多對多關系

Question

我試圖在一側使用ASP.NET身份表使用代碼優先EF來實現多對多關系。 但是，聯接表不是在數據庫中生成的。 我想念什么？ 這是我的模型類：

AppUser.cs：

public class AppUser : IdentityUser
{
    public AppUser()
    {
        Notes = new HashSet<Note>();
    }

    public DateTime? LastSuccessfulLoginDate { get; set; }

    public virtual ICollection<Note> Notes { get; set; }
}

和

Note.cs：

public class Note
{
    public Note() {

        NoteAssignedToUsers = new HashSet<AppUser>();
    }

    [Key]
    public int NoteID { get; set; }

    [Required]
    public int FileID { get; set; }

    [Required]
    public string Content { get; set; }

    [Required]
    public Importance? Importance { get; set; }

    [Required]
    [DisplayFormat(DataFormatString = "{0:dd.MM.yyyy HH.mm}")]
    public DateTime AddedOn { get; set; }

    [Required]
    public string CreatorID { get; set; }

    [ForeignKey("FileID")]
    public virtual OAFile OAFile { get; set; }

    [ForeignKey("CreatorID")]
    public virtual AppUser CreatedBy { get; set; }

    public virtual ICollection<AppUser> NoteAssignedToUsers { get; set; }
}

在您的dbcontext中，您可以配置：

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{

    modelBuilder.Entity<Note>()
                .HasMany<AppUser>(s => s.NoteAssignedToUsers )
                .WithMany(c => c.Notes)
                .Map(cs =>
                        {
                            cs.MapLeftKey("AppUserId");
                            cs.MapRightKey("NoteId");
                            cs.ToTable("AppUsersNotes");
                        });

}
