.netcore跨平臺 之 windows上編譯，ubuntu上運行

1 下載並安裝netcore sdk
    下載地址 https://github.com/dotnet/cli  

                       

      選取合適的版本下載安裝便可

     打開 CMD ，輸入dotnet，出現如下信息說明已安裝好

C:\Users\71700>dotnet
Usage: dotnet [--help | app.dll]

 2 新建一個項目 

新建項目在cmd 裏輸入dotnet new 便可

 

C:\Users\71700>mkdir demo

C:\Users\71700>cd demo

C:\Users\71700\demo>dotnet new
Created new C# project in C:\Users\71700\demo.

C:\Users\71700\demo>dir
 驅動器 C 中的卷沒有標籤。
 卷的序列號是 3A94-0B71

 C:\Users\71700\demo 的目錄

2016-04-25  14:58    <DIR>          .
2016-04-25  14:58    <DIR>          ..
2016-04-25  14:58               214 Program.cs
2016-04-25  14:58               308 project.json
               2 個文件            522 字節
               2 個目錄 87,409,934,336 可用字節

 

能夠看到共生成了兩個文件  program.cs和project.json 如下是內容
 Program.cs

using System;

namespace ConsoleApplication
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}

project.json

{
  "version": "1.0.0-*",
  "compilationOptions": {
    "emitEntryPoint": true
  },
  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.0-rc2-3002485"
    }
  },
  "frameworks": {
    "netcoreapp1.0": {
      "imports": "dnxcore50"
    }
  }
}

很簡單的兩個文件 ，就是要輸出hello world

3 修改project.json 來支持交叉編譯

{
  "version": "1.0.0-*",
  "compilationOptions": {
    "emitEntryPoint": true
  },
  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",     //此處去掉，加上的話發佈的時候不會netcore的運行環境和基礎類庫一塊發佈，須要在目標平臺上安裝netcore ,去掉的話就不用在目標平臺上安裝netcore了      
　　　 "version": "1.0.0-rc2-3002485"
    }
  },
  "frameworks": {
    "netcoreapp1.0": {
      "imports": "dnxcore50"
    }
  },
  "runtimes":{"ubuntu.15.04-x64":{}} //加入runtimes

}

 

 

4保存文件，還原引用包 運行dotnet restore

C:\Users\71700\demo>dotnet restore
log  : Restoring packages for C:\Users\71700\demo\project.json...

5 編譯代碼 dotnet build -r ubuntu.15.04-x64

C:\Users\71700\demo>dotnet build -r ubuntu.15.04-x64
Compiling demo for .NETCoreApp,Version=v1.0

Compilation succeeded.
0 Warning(s)
0 Error(s)

Time elapsed 00:00:01.4677989

6發佈程序 dotnet publish -r ubuntu.15.04-x64

C:\Users\71700\demo>dotnet publish -r ubuntu.15.04-x64
Publishing demo for .NETCoreApp,Version=v1.0/ubuntu.15.04-x64
Project demo (.NETCoreApp,Version=v1.0) was previously compiled. Skipping compilation.
publish: Published to C:\Users\71700\demo\bin\Debug\netcoreapp1.0\ubuntu.15.04-x64\publish
Published 1/1 projects successfully

查看下publish文件夾

文件不少，其中demo是ubuntu上的可執行文件

7把publish文件加拷貝的共享文件夾裏面 並掛載到ubuntu上 運行demo
 先ls查看下文件裏面的內容
