How to implement guide with json serialization in asp.net core web api causing 'circular reference' scenarios
I'm migrating some code and I'm getting frustrated with I'm working on an ASP.NET Core 6 Web API that returns a complex object graph, but I'm working with a 'circular reference' behavior when trying to serialize a response. My object model includes several navigation properties that create a loop, and when I try to return the main object, the serialization fails with the behavior message: ``` Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property 'Child' with type 'MyNamespace.ChildModel'. Path 'Parent.Child' ``` I have tried using `JsonIgnore` on the navigation properties, but it seems like I'm still running into issues. Here's a simplified version of my models: ```csharp public class ParentModel { public int Id { get; set; } public string Name { get; set; } public virtual ChildModel Child { get; set; } } public class ChildModel { public int Id { get; set; } public string Description { get; set; } public virtual ParentModel Parent { get; set; } } ``` Additionally, I've attempted to configure the JSON serialization settings in `Startup.cs` like this: ```csharp services.AddControllers() .AddNewtonsoftJson(options => { options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; }); ``` Despite these efforts, the circular reference still seems to continue during serialization. I've also looked into using `System.Text.Json`, but I prefer to stick with Newtonsoft.Json for now due to its flexibility in handling complex types. Is there a better approach or best practice to handle this kind of scenario in ASP.NET Core? Any insights would be greatly appreciated! I appreciate any insights! Thanks for your help in advance!
