c# – 在Linux上运行.NET Core – 什么都不写

ubuntu@ubuntu-Virtual-Machine:~/ConsoleApp2/src/ConsoleApp2$dnvm list

Active Version              Runtime Architecture OperatingSystem Alias

ubuntu@ubuntu-Virtual-Machine:~/ConsoleApp2/src/ConsoleApp2$dnu restore
ubuntu@ubuntu-Virtual-Machine:~/ConsoleApp2/src/ConsoleApp2$dnx run
ubuntu@ubuntu-Virtual-Machine:~/ConsoleApp2/src/ConsoleApp2$

我的应用程序没有运行.但是,如果我将dnvm切换为单声道,它可以正常工作.
我的文件内容是

Program.cs中

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace ConsoleApp2
{
    public class Program
    {
        public void Main(string[] args)
        {
            Console.WriteLine("Hello world!!!!");
            Console.Read();
        }
    }
}

project.json

{
  "version": "1.0.0-*","description": "ConsoleApp2 Console Application","authors": [ "Anton" ],"tags": [ "" ],"projectUrl": "","licenseUrl": "","dependencies": {

  },"frameworks": {
    "dnx451": {},"dnxcore50": {
      "dependencies": {

        "System.Console": "4.0.0-beta-23019","System.Linq": "4.0.0-beta-23019","System.Threading": "4.0.10-beta-23019","Microsoft.CSharp": "4.0.0-beta-23019"
      }
    }
  }
}

为什么dnx命令在切换到coreclr时什么都不写？
