Update to newer Newtonsoft or switch to System.Text.json

The version of Newtonsoft referenced has known vulnerabilities. Anyone referencing this has to also reference a newer version of Newtonsoft to clear security scans. My solution is Newtonsoft free and I'd rather not add packages for my dev teams to accidentally use. If possible I think it would be better to switch to System.Text.Json or extract serialization in a similar fashion to how database was done.

Thanks
