Setting up C# Development Environment

To write and compile C# programs on Ubuntu 22.04, you can use the .NET SDK, which is a free, open-source, and cross-platform framework for building modern, cloud-based, and internet-connected applications. Here are the steps to set up your environment and write/compile C# programs:

• Setting up C# Development Environment
  • Install .NET SDK:
• Compiling & Execution
  • Create a New Project:
  • Compiling the C# program
  • Execution

Install .NET SDK:

Open a terminal and follow these steps to install the .NET SDK:
First let us add the Microsoft package repository

$ wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb

$ sudo dpkg -i packages-microsoft-prod.deb

Next let us install the .NET SDK, for that run the following commands in the terminal.

$ sudo apt update
$ sudo apt install -y apt-transport-https
$ sudo apt update
$ sudo apt install -y dotnet-sdk-7.0

Compiling & Execution

Create a New Project:

Enter the following command to create a new project, the last parameter is your Project Name.

$ dotnet new console -n HelloCSharp

You can see a HelloCSharp folder created in your current directory. It will contain a file Program.cs that has a simple Hello World program. You can edit this file to write your own program.
Let us write the following code in the Program.cs file.

using System;  
  
class Program  
{  
    static void Main()  
    {  
        Console.WriteLine("Hello, Ubuntu 22.04!");  
    }  
}  

Now save the file.

Compiling the C# program

To compile the C# program, use the following command:

$ dotnet build -o out HelloCSharp.csproj

Execution

To execute the C# program, use the following command:

$ ./out/HelloCSharp

After running the program you should see the following output.

$ ./out/HelloCSharp 
Hello, Ubuntu 22.04!
