How can a JSON serialize detect a potential object cycle in .NET MAUI?

edit

In .NET MAUI, a JSON serializer can detect a potential object cycle by using the built-in JsonSerializerSettings object. Specifically, the JsonSerializerSettings object has a property called ReferenceLoopHandling, which controls how the serializer handles circular references.

The ReferenceLoopHandling property can be set to Ignore, Serialize, or Error. If set to Ignore, circular references will be ignored and not serialized. If set to Serialize, circular references will be serialized as an object reference. If set to Error, the serializer will throw an exception when it detects a circular reference.

For example, the following code snippet shows how to configure a JsonSerializerSettings object to handle circular references:

JsonSerializerSettings settings = new JsonSerializerSettings
{
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore
};

string json = JsonConvert.SerializeObject(myObject, Formatting.None, settings);

In this example, the ReferenceLoopHandling property is set to Ignore, which means that circular references will be ignored and not serialized. If a circular reference is detected, the serializer will simply skip that object and move on to the next one.
