前言

NuGet 是免费、开源的包管理开发工具，专注于在 .NET 应用开发过程中，简单地合并第三方的组件库。今天的目的就是记录一下如何打包一个类库，并发布到官网。在开始之前需要在www.nuget.org上注册一个账号，下载最新版本的nuget命令行工具https://dist.nuget.org/win-x86-commandline/latest/nuget.exe,并添加到环境变量中。

开始打包自己的类库

1.修改项目程序集信息AssemblyInfo.cs

我这里要打包的类库Zeroes.WeixinSDK来源于https://github.com/night-king/weixinSDK开源项目，修改完信息后重新生成一下。

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("Zeroes.WeixinSDK")]
[assembly: AssemblyDescription("ZeroesSuit快速开发框架微信SDK库")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("Zeroes")]
[assembly: AssemblyProduct("Zeroes.WeixinSDK")]
[assembly: AssemblyCopyright("Copyright © Microsoft 2016")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("135e92df-8241-4d2c-97aa-910e1c53af81")]

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Build and Revision Numbers 
// by using the '*' as shown below:
// [assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyVersion("0.0.0.1")]
[assembly: AssemblyFileVersion("0.0.0.1")]

2.命令行下使用nuget spec命令生成Zeroes.WeixinSDK.nuspec打包配置文件

打开命令行定位到Zeroes.WeixinSDK项目所在目录，输入命令：nuget spec

修改生成的nuspec文件，内容如下：

<?xml version="1.0"?>
<package >
  <metadata>
    <id>$id$</id>
    <version>$version$</version>
    <title>$title$</title>

    <releaseNotes>Zeroes.WeixinSDK封装了微信api的调用方法,可以方便的调用。</releaseNotes>

    <tags>Zeroes</tags>
  </metadata>
</package>

3.打包类库

打开命令行定位到Zeroes.WeixinSDK项目所在目录，输入命令：nuget pack Zeroes.WeixinSDK.csproj

4.发布类库

登陆www.nuget.org网站，打开https://www.nuget.org/packages/manage/upload地址。

点击“Upload”上传后，显示信息确认页面，然后点击 “Submit”，发布完成

5.使用nuget安装类库
