Migrate from Newtonsoft.Json to System.Text.Json

[anthonyreilly]

Newtonsoft.Json is effectively a legacy library, now that .NET has updated it's native JSON support, migration for performance and support reasons would probably be a good idea.

Currently no direct replacement for DefaultContractResolver, may need custom implementation
dotnet/runtime#31257

any update on this now that System.Text.Json has more features? Custom Contracts can be defined.

Thanks for the link - I was waiting for something like that to be added. I'll check it out and see if it will work - I've wanted to migrate away from the old JSON library for a while now.

Hi @anthonyreilly -
Do you think you can get this implemented now that .NET 8.0 is out?

By the way, thank you so much for your work with this library.
