如何首先使用mvc 5和EntityFramework代码将两个属性映射到同一张表？

我上这堂课。

public class ApplicationUser : IdentityUser
{
    [Required]
    [DataType(DataType.EmailAddress)]
    public string Email { get; set; }

    public virtual ICollection<Post> PostsCreated { get; set; }
    public virtual ICollection<Post> PostsModified { get; set; }
    public virtual Comment Comment { get; set; }
}

而另一类是...

public class Post
{
    public int PostId { get; set; }
    public string Title { get; set; }
    public string Body { get; set; }
    public virtual ICollection<Category> Category { get; set; }

    public DateTime PublishDate { get; set; }
    public DateTime CreateDate { get; set; }
    //----------------------------------------------------------------
    [ForeignKey("UserCreated"), Column(Order = 0)]
    public string CreatedId { get; set; }

    [ForeignKey("UserModify"), Column(Order = 1)]
    public string ModifiedId { get; set; }
    //----------------------------------------------------------------
    [InverseProperty("PostsCreated")]
    public virtual ICollection<ApplicationUser> UserCreated { get; set; }

    [InverseProperty("PostsModified")]
    public virtual ICollection<ApplicationUser> UserModify { get; set; }
    //----------------------------------------------------------------
    public DateTime ModifiedDate { get; set; }
    public Public Public { get; set; }
}

我的数据访问权限是这个.....

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("BlogLibrary2")
    {
    }
    public DbSet<Post> Post { get; set; }
    public DbSet<Comment> Comment { get; set; }
    public DbSet<Category> Category { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
    }
}

当我尝试使用此数据访问和Post类创建控制器时，出现了此错误：

运行所选代码生成器时发生错误：“无法检索'LibraryBlog.Models.Post”的元数据。外键组件'CreatedId'不是类型为'ApplicationUser'的已声明属性。请验证未将其显式排除在模型之外，并且它是有效的原始属性。
