Handling JSON Serialization of Circular References in C# - implementing Newtonsoft.Json
I'm migrating some code and I'm deploying to production and Can someone help me understand I'm stuck on something that should probably be simple....... I'm working with a scenario with JSON serialization using Newtonsoft.Json (version 13.0.1) in a C# application. My object models have circular references, and when I try to serialize one of them, I get the following behavior: `Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property 'Parent' with value 'SomeObject'`. I've tried using the `ReferenceLoopHandling` setting in my `JsonSerializerSettings`, but it doesn't seem to work as expected. Here's a simplified version of my object model: ```csharp public class Person { public string Name { get; set; } public Person Parent { get; set; } } ``` When I try to serialize an instance of `Person` where `Parent` points back to another instance of `Person`, I'm unable to avoid the circular reference scenario. I've set up my serializer like this: ```csharp var settings = new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore }; var json = JsonConvert.SerializeObject(person, settings); ``` Despite using `ReferenceLoopHandling.Ignore`, I'm still getting the same exception. I've also considered using `StringEnumConverter` but it doesn't apply here since I'm not dealing with enums. I would appreciate any insights on how to effectively handle this scenario without running into serialization errors. Is there a specific configuration or approach that I might be missing? Thanks in advance! My development environment is Linux. Any ideas what could be causing this? I'm working on a mobile app that needs to handle this. Hoping someone can shed some light on this. I'm on Ubuntu 22.04 using the latest version of C#. Any examples would be super helpful. I've been using C# for about a year now.
