似乎与aspnetuser无关，外键冲突

Question

我正在尝试与初始aspnetusers设置建立一对多关系。似乎无法使其正常工作，有人知道如何修复它吗？

public class ApplicationUser:IdentityUser
{
    public virtual ICollection<UserMovieData> UserMovieDatas { get; set; }
}

public class UserMovieData
{
    public int UserMovieDataId { get; set; }
    public string ImdbId { get; set; }
    public bool Favorited { get; set; }
    public double Rating { get; set; }
    public string Review { get; set; }
    public string ApplicationUserId { get; set; }

    public virtual ApplicationUser ApplicationUser { get; set; }
}

modelBuilder.Entity<UserMovieData>()
            .HasOne(p => p.ApplicationUser)
            .WithMany(b => b.UserMovieDatas)
            .HasForeignKey(p => p.ApplicationUserId);

错误：

  

ALTER TABLE语句与FOREIGN KEY约束“ FK_UserMovieData_AspNetUsers_applicationUserId”冲突。在数据库“ ____”，表“ dbo.AspNetUsers”的“ Id”列中发生了冲突。
