implementing JSON Serialization of Complex Objects with System.Text.Json in .NET 6
I'm having trouble with I'm working with issues with serializing complex objects that include circular references using `System.Text.Json` in .NET 6... Whenever I attempt to serialize an object that contains navigation properties referencing back to the parent object, I get the following behavior: `System.Text.Json.JsonException: A possible object cycle was detected which is not supported in JSON serialization.`. I've tried using the `ReferenceHandler` options, but it doesn't seem to be working as expected. Here's a simplified version of the classes I'm working with: ```csharp public class Employee { public int Id { get; set; } public string Name { get; set; } public Employee Manager { get; set; } } public class Department { public string Name { get; set; } public List<Employee> Employees { get; set; } } ``` When I try to serialize an instance of `Department` that contains `Employee` objects with circular references, like so: ```csharp var department = new Department { Name = "Sales", Employees = new List<Employee> { new Employee { Id = 1, Name = "Alice" }, new Employee { Id = 2, Name = "Bob", Manager = department.Employees[0] } } }; var options = new JsonSerializerOptions { ReferenceHandler = ReferenceHandler.Preserve, }; string json = JsonSerializer.Serialize(department, options); ``` I was expecting the serialization to handle the circular reference gracefully, but instead, I still encounter the JSON exception. I have confirmed that I'm on .NET 6.0.100 and have the latest updates installed. I've reviewed the documentation but haven't found a solution that fits my use case. Any insights or alternative approaches would be greatly appreciated! I'm on macOS using the latest version of Csharp. Any pointers in the right direction? Any help would be greatly appreciated!
