CSharp scripting with nuget referencing.

// Make sure you define the version of Nuget package for caching!

#r "nuget: Newtonsoft.Json, 12.0.3"

using System;
using Newtonsoft.Json;


class Product
{
	public Guid Id{get;set;}
	public string Name{get;set;}
	public bool Enabled{get;set;}
}

var productObj = new Product {
	Id = Guid.NewGuid(),
	Name = "FooBar",
	Enabled = true
};


Console.WriteLine(JsonConvert.SerializeObject(productObj));

You can also deserialize JSON to a dynamic object:

using Newtonsoft.Json.Linq;

dynamic json = JObject.Parse("{'Id':1,'Name':'FooBar','Enabled':true}");
Console.WriteLine($"Id: {json.Id}");
Console.WriteLine($"Name: {json.Name}");
Console.WriteLine($"Enabled: {json.Enabled}");
