无法将动态类型与asp.net vnext核心一起使用

您需要为aspnetcore50框架包含包Microsoft.CSharp和System.Dynamic.Runtime。

对于CoreCLR 1.0.0-beta1版本，这似乎对我有用：

using Newtonsoft.Json.Linq;
using System;

namespace DynamicTest
{
    public class Program
    {
        public void Main(string[] args)
        {

            dynamic dobject = JObject.Parse("{number:1000, str:'string', array: [1,2,3,4,5,6]}");

            Console.WriteLine(dobject.number);
            Console.WriteLine(dobject.str);
            Console.WriteLine(dobject.array.Count);
            Console.ReadLine();
        }
    }
}

project.json

{
    "version": "1.0.0-*",
    "dependencies": {
        "Newtonsoft.Json" :  "6.0.7"
    },
    "commands": { 
        "run" : "run"
    },
    "frameworks" : {
        "aspnet50" : { },
        "aspnetcore50" : { 
            "dependencies": {
                "System.Console": "4.0.0-beta-22231",
                "System.Dynamic.Runtime": "4.0.0-beta-22231",
                "Microsoft.CSharp": "4.0.0-beta-22231"
            }
        }
    }
}
