Topshelf注册windows服务，方便快捷
我们经常会用一些定时处理的任务，在.net种一般是结合Quartz或者hangfire这两个组件实现定时周期性作业，但是我想把开发好的定时作业注册成windows服务，这样，在服务器重启之后，可以自动运行服务。Topshelf 就可以很方便的开发windows，而且注册安装也很方便。
TopShelf的地址：http://topshelf-project.com/
我们首先使用netget安装TopShelf：
1
| Install-Package TopShelf
|
然后在program.cs中加入如下代码：

StartAsync方法为服务启动时运行。然后编译程序：
1
| dotnet publish -o ./bin/output -c Release -r win7-x64
|
执行成功后，会在bin/output目录下生成运行所需要的的程序和依赖DLL。将整个目录复制到指定服务器，cmd进入到程序目录，执行：
就可以完成服务安装.
执行:
就可以完成服务卸载，非常方便。
