Remove dependency on 3rd party JSON library from next version of runtime about openwhisk-runtime-dotnet HOT 1 OPEN

I decided to test this out and include an example if I got it working. Yep, it works! #52 shows the changes I made to the 3.1 runtime to make it work without Newtonsoft.Json on the action side of things (JSON is still needed on the runtime side of things, in order to fulfill its contract with the OpenWhisk system which speaks JSON).

My build of the changed runtime is public at https://hub.docker.com/repository/docker/mwelke/openwhisk-runtime-dotnet-v3.1-nojson if anyone wants to play with it.

I made a test action to demonstrate it (https://github.com/mattwelke/openwhisk-dotnet-runtime-v3.1-nojson-test). deploy.sh in that repo shows how I deployed it to IBM Cloud Function as a custom runtime action (after logging into ibmcloud CLI).

For convenience, here's the code repeated here for my action in that repo:

using System.Collections.Generic;

namespace OpenWhiskDotnetNoJsonTest
{
    public class Class1
    {
        public Dictionary<string, object> Main(Dictionary<string, object> owParams)
        {
            var output = new Dictionary<string, object>();
            foreach (var owParam in owParams)
            {
                output.Add(owParam.Key, owParam.Value);
            }

            output.Add("success", true);
            
            return output;
        }
    }
}

I configured a parameter:

And it works! It has access to the parameter, and returns things to OpenWhisk nicely (via Dictionary):
