Answer 1

내 viewcomponent 모달 클래스에 몇 가지 태그를 추가하여 문제를 해결하고

[JsonObject(MemberSerialization.OptIn)] 및 [JsonProperty] 같은 설정 속성을 가져가

//Tag to add only selected property when Deserialize or Serialize using Newtonsoft 
    [JsonObject(MemberSerialization.OptIn)] 
    public class HeaderTopViewComponent:ViewComponent 
    { 
     #region //Property// 
     [JsonProperty] 
     public bool ShowTopheaderSection { get; set; } 
     [JsonProperty] 
     public string PageHeader { get; set; } 
     [JsonProperty] 
     public string FriendlyURL { get; set; } 
     [JsonProperty] 

그리고 지금은 작동
