    Official Website:https://www.microsoft.com/net/learn/get-started-with-dotnet-tutorial#install

    Windows

    Install the .NET SDK

    To start building .NET apps you just need to download and install the .NET SDK (Software Development Kit).

     
    1. Create your app

      Open a new command prompt and run the following commands:

      dotnet new console -o myApp
      cd myApp

      The dotnet command creates a new application of type console for you. The -o parameter creates a directory named myApp where your app is stored, and populates it with the required files. The cd myApp command puts you into the newly created app directory.

      The main file in the myApp folder is Program.cs. By default, it already contains the necessary code to write "Hello World!" to the Console.

      using System;
      
      namespace myApp
      {
          class Program
          {
              static void Main(string[] args)
              {
                  Console.WriteLine("Hello World!");
              }
          }
      }
    2. Run your app

      In your command prompt, run the following command:

      dotnet run

      Congratulations, you've built and run your first .NET app!

    3. Get an editor

      Visual Studio is a fully-featured integrated development environment (IDE) for developing .NET apps on Windows.

    4. Keep learning

      Now that you've got the basics, you can keep learning with the .NET Quick Starts. In the first Quick Start you'll learn about collections.

    Linux

    Install the .NET SDK

    To start building .NET apps you just need to download and install the .NET SDK (Software Development Kit).

    Linux Distribution

     
      1. Enable .NET channel

        In order to install .NET Core from Red Hat on RHEL, you first need to register using the Red Hat Subscription Manager. If this has not been done on your system, or if you are unsure, see the Red Hat Getting Started Guide.

        Install .NET SDK

        After registering with the Subscription Manager and enabling the .NET Core channel, you are ready to install and enable the .NET SDK.

        In your command prompt, run the following commands:

        yum install rh-dotnet21 -y
        scl enable rh-dotnet21 bash
        
      2. Create your app

        Open a new command prompt and run the following commands:

        dotnet new console -o myApp
        cd myApp

        The dotnet command creates a new application of type console for you. The -o parameter creates a directory named myApp where your app is stored, and populates it with the required files. The cd myApp command puts you into the newly created app directory.

        The main file in the myApp folder is Program.cs. By default, it already contains the necessary code to write "Hello World!" to the Console.

        using System;
        
        namespace myApp
        {
            class Program
            {
                static void Main(string[] args)
                {
                    Console.WriteLine("Hello World!");
                }
            }
        }
      3. Run your app

        In your command prompt, run the following command:

        dotnet run

        Congratulations, you've built and run your first .NET app!

      4. Get an editor

        Visual Studio Code is a free, cross-platform code editor with support for .NET.

    For full language support including smart code completion and debugging, get the C# extension for Visual Studio Code.

    1. Keep learning

      Now that you've got the basics, you can keep learning with the .NET Quick Starts. In the first Quick Start you'll learn about collections.
