本文共 8009 字，大约阅读时间需要 26 分钟。

1 下载并安装netcore sdk

下载地址 https://github.com/dotnet/cli

选取合适的版本下载安装即可

打开 CMD ，输入dotnet，出现以下信息说明已安装好

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

2 新建一个项目

新建项目在cmd 里输入dotnet new 即可

C:\Users\71700>mkdir demoC:\Users\71700>cd demoC:\Users\71700\demo>dotnet newCreated new C# project in C:\Users\71700\demo.C:\Users\71700\demo>dir 驱动器 C 中的卷没有标签。 卷的序列号是 3A94-0B71 C:\Users\71700\demo 的目录2016-04-25  14:58    
    
               .2016-04-25  14:58    
     
                ..2016-04-25  14:58               214 Program.cs2016-04-25  14:58               308 project.json               2 个文件            522 字节               2 个目录 87,409,934,336 可用字节

可以看到共生成了两个文件 program.cs和project.json 以下是内容

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"    }  }}

很简单的两个文件，就是要输出hello world

3 修改project.json 来支持交叉编译

{  "version": "1.0.0-*",  "compilationOptions": {    "emitEntryPoint": true  },  "dependencies": {    "Microsoft.NETCore.App": {      "type": "platform",     //此处去掉，加上的话发布的时候不会netcore的运行环境和基础类库一块发布，需要在目标平台上安装netcore ,去掉的话就不用在目标平台上安装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，还原引用包运行dotnet restore

C:\Users\71700\demo>dotnet restorelog  : Restoring packages for C:\Users\71700\demo\project.json...info :   GET https://api.nuget.org/v3-flatcontainer/microsoft.netcore.dotnethostresolver/index.jsoninfo :   CACHE https://dotnetmyget.blob.core.windows.net/artifacts/dotnet-core/nuget/v3/flatcontainer/microsoft.netcore.dotnethostresolver/index.jsoninfo :   NotFound https://api.nuget.org/v3-flatcontainer/microsoft.netcore.dotnethostresolver/index.json 1208msinfo :   CACHE https://dotnetmyget.blob.core.windows.net/artifacts/dotnet-core/nuget/v3/flatcontainer/microsoft.netcore.dotnethost/index.jsoninfo :   GET https://api.nuget.org/v3-flatcontainer/microsoft.netcore.dotnethost/index.jsoninfo :   NotFound https://api.nuget.org/v3-flatcontainer/microsoft.netcore.dotnethost/index.json 1935msinfo : Committing restore...log  : Writing lock file to disk.

5 编译代码 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发布程序 dotnet publish -r ubuntu.15.04-x64

C:\Users\71700\demo>dotnet publish -r ubuntu.15.04-x64Publishing demo for .NETCoreApp,Version=v1.0/ubuntu.15.04-x64Project 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\publishPublished 1/1 projects successfully

查看下publish文件夹

文件很多，其中demo是ubuntu上的可执行文件

7把publish文件加拷贝的共享文件夹里面并挂载到ubuntu上运行demo

先ls查看下文件里面的内容

成功输出 helloworld
