ef core 创建自引用灰了了

public class Menu:IEntity { public int Id { get; set; } public string text { get; set; } public bool group { get; set; } public bool shortout_root { get; set; } public string link { get; set; } public string icon { get; set; } public bool linkExact { get; set; } public virtual List<Menu> children { get; set; } public virtual int? parentId { get; set; } public virtual Menu? parent { get; set; } public List<UserMenu> UserMenu { get; set; } }

报错：System.Text.Json.JsonException: A possible object cycle was detected which is not supported. This can either be due to a cycle or if the object depth is larger than the maximum allowed depth of 32

检测到不撑持的可能东西循环。这可能是由于周期或物体深度大于最大允许深度32。

解决：添加 Microsoft.AspNetCore.Mvc.NewtonsoftJson 包后正常，，但引用的深度就对照深了
