MVC .Net Cascade在使用EF Code First Approach时删除

public class Blog
    {
        [Key]
        public int Id { get; set; }
        [Required]
        public string Name { get; set; }
        [DisplayFormat()]
        public virtual ICollection<BlogEntry> BlogEntries { get; set; }
        public DateTime CreationDateTime { get; set; }
        public string UserName { get; set; }
    }

    public class BlogEntry
    {
        [Key]
        public int Id { get; set; }
        [Required]
        public string Title { get; set; }
        [Required]
        public string Summary { get; set; }
        [Required]
        public string Body { get; set; }
        public List<Comment> Comments { get; set; }
        public List<Tag> Tags { get; set; }
        public DateTime CreationDateTime { get; set; }
        public DateTime UpdateDateTime { get; set; }
        public virtual Blog ParentBlog { get; set; }

    }

对于我的控制器,我设置他在删除帖子后继续：

[HttpPost,ActionName("Delete")]
public ActionResult DeleteConfirmed(int id)
{
    Blag blog = db.Blogs.Find(id);

    foreach (var blogentry in blog.BlogEntries)
    {
        //blogentry = db.BlogEntries.Find(id);
        db.BlogEntries.Remove(blogentry);
    }
    db.Blogs.Remove(blog);
    db.SaveChanges();
    return RedirectToAction("Index");
}

问题是无论如何都不会工作I read this post但是我似乎只适用于关系是一对一的模型,所以我在这里失去了,我有无处不在的搜索,找不到这个问题的解决方案,如果有人可以指出我错过了什么这真的很好:),谢谢提前,再次,赦免我的nooobness我刚刚开始,但想要解决一个大项目,以能够学到很多.
