How to process the references serialization in System.Json.Text

[ym9288]

I have a class like blow
`class A
{
public B {get;set;}
}
class C
{
public B {get;set;}
}

Now the target to serialize is like this:
var b = new B();
var a = new A(){
B = b
}
var c = new C(){
B = b
}
var serializeTarget = new List{a, c}
`
I used ReferenceHandler.Preserve as my ReferenceHandler, but when i check the json result, I found that the instance: b was serialized twice, and i found that the "$id" generated seems like reset to 1 when i call blow methow in my JsonConverter

I doubt it cause by the "ReferenceHandler.CreateResolver()",

I write a custom Referencehandler to return a sington resolver hope to resolve this


Now it seems OK, but when I deserialize the result json, it gives me:


It seems caused by this node {"$ref"...}
