C#(Dotnet) Setup in Ubuntu with VSCode
Installation and Creating a simple C-Sharp Program
C# is a general-purpose, multi-paradigm programming language encompassing static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented, and component-oriented programming disciplines.
In this article, I will take you through installing and setting up C#(c-sharp) environment on a Ubuntu OS(Operating System).
Requirements:
- Ubuntu OS (20.0 and above)
- Internet Connection (For Installation)
- Command Line Skills (for the obvious LOL)
- Visual Studio Code
Note that .NET is a C# library
Installing .NET (Csharp)
Start your terminal on Ubuntu;
ctr
+ shift
+ T
First we need to add the Microsoft package signing key to your list of trusted keys and add the package repository. Run the commands in the order as they appear;
wget https://packages.microsoft.com/config/ubuntu/21.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
Installing .NET SDK
sudo apt-get update; \
sudo apt-get install -y apt-transport-https && \
sudo apt-get update && \
sudo apt-get install -y dotnet-sdk-5.0
Installing The Runtime
sudo apt-get update; \
sudo apt-get install -y apt-transport-https && \
sudo apt-get update && \
sudo apt-get install -y aspnetcore-runtime-5.0
To test the installation, run the command dotnet
on your terminal;
dotnet
yaay! we are done with that.
Visual Studio Code Setup
This is an easy procedure, as we only need to install an extension on VSCode.
The extension is: C# for Visual Studio Code (powered by OmniSharp)
How to Install VSCode Extensions:
Once you have the extension added, we can create the famous Hello World application in C#.
Creating Hello World in C
First you create a new Project folder, say c-sharp
, and open the empty folder with Visual Studio Code.
Open the integrated terminal in VSCode or use the terminal (ensure you are in the project's folder path).
To start a C# program use the command below;
dotnet new console
dotnet new
is creating a new dotnet project. console
is to specify the application type, in this case our program will be running on our terminal (console).
Once you run the command, a couple of files and folders are created.
We are only interested in the Program.cs
file for now:
using System;
namespace hello
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
}
}
}
You don't need to change anything for now.
Let's run the program using the command:
dotnet run
And that is how you get to use C# in Ubuntu.

Don't mind my terminal name, my laptop is really slow LOL!
