The **.NET Core** is a free, cross platform and open source framework developed by Microsoft to build desktop applications, mobile apps, web apps, IoT apps and gaming apps etc. If you’re dotnet developer coming from Windows platform, .NET core helps you to setup your development environment easily on any Linux and Unix-like operating systems. This step by step guide explains how to install Microsoft .NET Core SDK on Linux and how to write your first app using .Net. **.NET Core** 是微软提供的免费、跨平台和开源的开发框架，可以构建桌面应用程序、移动端应用程序、网络应用程序、物联网应用程序和游戏应用程序等。如果你是 Windows 平台下的 dotnet 开发人员的话，使用 .NET core 可以很轻松就设置好任何 Linux 和类 Unix 操作系统下的开发环境。本分步操作指南文章解释了如何在 Linux 中安装 .NET Core SDK 以及如何使用 .NET 开发出第一个应用程序。
### Install Microsoft .NET Core SDK On Linux ### Linux 中安装 .NET Core SDK
The .NET core supports GNU/Linux, Mac OS and Windows. .Net core can be installed on popular GNU/Linux operating systems including Debian, Fedora, CentOS, Oracle Linux, RHEL, SUSE/openSUSE, and Ubuntu.

### Create Your First App ### 创建你的第一个应用程序
We have successfully installed .Net Core SDK in our Linux box. It is time to create our first app using dotnet. 我们已经成功的在 Linux 机器中安装了 .NET Core SDK。是时候使用 dotnet 创建第一个应用程序了。
For the purpose of this guide, I am going to create a new app called **“ostechnixApp”**. To do so, simply run the following command: 接下来的目的，我们会创建一个名为 **“ostechnixApp”** 的应用程序。为此，可以简单的运行如下命令：
``` ```
$ dotnet new console -o ostechnixApp $ dotnet new console -o ostechnixApp

Open the Program.cs file in your favorite editor, delete or modify the existing ‘hello world’ code with your own code. 上的命令会创建两个名叫 **mycode.csproj** 和 **Program.cs** 的文件及一个名为 **obj** 的目录。用你喜欢的编辑器打开 `Program.cs` 文件, 删除或修改原来的 'hello world' 代码段，然后编写自己的代码。
Once the code is written, save and close the Program.cs file and run the app using command: 写完代码，保存，关闭 Program.cs 文件，然后运行此应用程序，命令如下：
``` ```
$ dotnet run $ dotnet run

### Get Microsoft Visual Studio Code Editor ### 使用微软的 Visual Studio Code 编辑器
To write the code, you can use your favorite editors of your choice. Microsoft has also its own editor named “ **Microsoft Visual Studio Code** ” with support for .NET. It is an open source, lightweight and powerful source code editor. It comes with built-in support for JavaScript, TypeScript and Node.js and has a rich ecosystem of extensions for other languages (such as C++, C#, Python, PHP, Go) and runtimes (such as .NET and Unity). It is a cross-platform code editor, so you can use it in Microsoft Windows, GNU/Linux, and Mac OS X. You can use it if you’re interested. 要编写代码，你可以任选自己喜欢的编辑器。同时微软自己也有一款支持 .NET 的编辑器，其名为 “ **Microsoft Visual Studio Code** ”。它是一款开源、轻量级、功能强大的源代码编辑器。其内置了对 JavaScript、TypeScript 和 Node.js 的支持，并为其它语言（如 C++、C#、Python、PHP、Go）和运行时态（如 .NET 和 Unity）提供了丰富的扩展，已经形成一个完整的生态系统。它是一款跨平台的代码编辑器，所以在微软的 Windows 系统、GNU/Linux 系统和 Mac OS X 系统都可以使用。如果对其感兴趣，就可以使用。

### Telemetry ### Telemetry
By default, the .NET core SDK will collect the usage data using a feature called **‘Telemetry’**. The collected data is anonymous and shared to the development team and community under the [Creative Commons Attribution License][2]. So the .NET team will understand how the tools are used and decide how they can be improved over time. If you don’t want to share your usage information, you can simply opt-out of telemetry by setting the **DOTNET_CLI_TELEMETRY_OPTOUT** environment variable to **‘1’** or **‘true’** using your favorite shell. 默认情况下，.NET core SDK 会采集用户使用情况数据，此功能被称为 **‘Telemetry’**。采集数据是匿名的，并根据[知识共享署名许可][2]分享给其开发团队和社区。因此 .NET 团队会知道这些工具的使用状况，然后根据统计做出决策，改进产品。如果你不想分享自己的使用信息的话，可以使用顺手的 shell 工具把名为 **DOTNET_CLI_TELEMETRY_OPTOUT** 的环境变量参数设置为 **‘1’** 或 **‘true’**，这样就简单的关闭此功能了。
And, that’s all. You know how to install .NET Core SDK on various Linux platforms and how to create a basic app using it. TO learn more about .NET usage, refer the links given at the end of this guide. 就这样。你已经知道如何在各 Linux 平台上安装 .NET Core SDK 以及知道如何创建基本的应用程序了。想了解更多 .NET 使用知识的话，请参阅此文章末尾给出的链接。
