Review comment:
Right now, because the runtime depends on version 12.0.2 in particular,
the instructions for making an action that uses the runtime say that the user
must add a dependency to version 12.0.2 in particular of Newtonsoft.Json to
their action project. Examples:
https://github.com/apache/openwhisk-runtime-dotnet/blob/master/core/dotnet3.1/QUICKSTART.md
https://cloud.ibm.com/docs/openwhisk?topic=openwhisk-prep#prep_dotnet (a
particular provider of OpenWhisk as a service)
Doesn't this mean that for OpenWhisk operators and providers, when they
update their version of the 3.1 runtime, they would want their users to be able
to continue deploying actions made for previous versions of the 3.1 runtime
without having to make changes (that runtime version updates are non-breaking)?
If so, we would need to stick to version 12.0.2 of Newtonsoft.Json.
I think the change that @kamyker made to use the built in System.Text.Json
instead improves this situation, because there's no 3rd party library for the
runtime and actions to need to be in sync with. The earliest version of .NET
that System.Text.Json was available in was 3.1 (then known as .NET Core)
(https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-migrate-from-newtonsoft-how-to?pivots=dotnet-5-0),
but it wasn't used here for the 3.1 runtime. So, if my understanding of our
semver problem is true, then we're stuck with Newtonsoft.Json for the 3.1
runtime, but we could look into using it for the next runtime (6.0 as you
state).
I think a better solution btw for the JSON problem is instead if having the
actions and runtimes depend on a third party JSON library, create a library
managed by OpenWhisk which has a class representing the data that the action's
Main method must return. The library could be called the "dotnet6.0 action
contract" library etc.
That way, all versions of the runtime and every action ever created for the
runtime can depend on the same major version of that library. The runtime would
control the implementation of how JSON is handled. It could choose for example
between different versions of Newtonsoft.Json or even other JSON libraries like
System.Text.Json whenever it wants, with the runtime versions being updated
without the action implementers ever having to worry about it.
