Packaging tasks should avoid using Newtonsoft.Json
We should switch to the new json reader/writer APIs. /cc @joperezr
FYI I think this is needed for source build. /cc @chcosta
Makes sense. Is there a deadline for when this needs to be done? (perhaps a deadline on source build?) I ask because I know that there is still some backlog on System.Text.Json API, and AFAIK the available API today is very low-level, so I wonder if we should wait till wrapper classes are built on top of the existing API.
We determined that it is not required for source build, so it's no longer a dependency we need to drive for 3.0. I'd see this more as dogfooding / best-practice.
