获取 SDK

搜索“下载 .net core”，在微软为你所在平台提供的下载页面，获取 .NET Core 的 SDK。完成 SDK 的安装后，开启一个终端窗口（或者 Windows 上的 PowerShell），并使用 dotnet 命令行工具（command line tool，也叫 CLI）确保一切正常工作：

  1. dotnet --version
  3. 2.1.104

还可以通过 --info 选项，获取你所在平台更详细的信息：

  1. dotnet --info
  3. .NET Command Line Tools (2.1.104)
  5. Product Information:
  6.  Version:            2.1.104
  7.  Commit SHA-1 hash:  48ec687460
  9. Runtime Environment:
  10.  OS Name:     Mac OS X
  11.  OS Version:  10.13
  13. (more details...)

如果你看到类似于上面的输出，就大步前进吧。
