记录在EF Core级联更新时出现的错误The database operation was expected to affect 1 row(s), but actually affected 0 row(s) （低级错误导致）

错误提示：The database operation was expected to affect 1 row(s), but actually affected 0 row(s); data may have been modified or deleted since entities were loaded. See http://go.microsoft.com/fwlink/?LinkId=527962 for information on understanding and handling optimistic concurrency exceptions.

需求很简单，我有一个主表Module 模块表，有一个子表Menu菜单，我想要通过Module实体级联更新Menu表，Menu对象由前端直接传值给我

代码如下：

接口代码

[HttpPut]
       public void HttpPut()
       {
           Module module = _context.modules.Include(x => x.List).FirstOrDefault(x => x.Guid == Guid.Parse("1e8c7053-8323-4438-af75-94afabeb9d7e"));
           module.List.Clear();
           var menu = new Menu { Name = "345", Guid = Guid.NewGuid() };
           module.List.Add(menu);
           _context.SaveChanges();
       }

　　实体代码

[Table("Menu")]
   public class Menu
   {
       [Key]
       public Guid Guid { get; set; }
 
       public Module Module { get; set; }
       public string Name { get; set; }
   }
 [Table("Module")]<br>
   public class Module
   {
       public Module()
       {
           List = new List<Menu>();
       }
       [Key]
       public Guid Guid { get; set; }
       public string Name { get; set; }
 
       [ConcurrencyCheck]
       public List<Menu> List { get; set; }
   }

　　看似平平无常的代码，却一直提示了出错，搜索了一些相关的文章，也没有找的对应的解决方案，最后在官方文档中找到了对应的例子

官方示例代码如下：

using (var context = new BloggingContext())
{
    var blog = context.Blogs.Include(b => b.Posts).First();
    var post = new Post { Title = "Intro to EF Core" };
 
    blog.Posts.Add(post);
    context.SaveChanges();
}
