我是实体框架的新手，所以如果这不是一个有效的问题，我深表歉意。
几周前我开始使用 .NET Web Api，当我必须处理更复杂的实体时，我遇到了 json 序列化的问题。经过一番研究，我发现了不同的方法，例如：
全球.asax.cs
GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling= Newtonsoft.Json.ReferenceLoopHandling.Ignore;
或者
对于我不想序列化的每个属性（在 context.designer.cs 文件中），添加：
[JsonIgnore]
第一个对我不起作用，所以我使用了 [JsonIgnore] 属性。
不幸的是，每隔一段时间我必须对实体框架上下文设计进行更改，一旦我保存这些更改，我就会丢失我添加到我不想序列化的属性的属性。
那么问题是：有没有办法将 JsonIgnore 永久设置为特定属性？或者防止实体框架覆盖特定属性或类的更改的方法？
甚至...... JsonIgnore 是最好的方法吗？
谢谢
