C# is a widely used language for many reasons. C# is a cross-platform programming language that can be run on multiple platforms, including desktop applications, websites, and Android applications. C# is not a difficult language to learn, it is an object-oriented programming language like java and python. As you may be hesitating on which language to choose, I decided to write this article to give you more details about C# language and help you decide whether to choose this language or not.

What is C#?

C# is pronounced C-sharp, it is a modern general-purpose language that can be used to perform different tasks and create applications that can be run on different devices and operating systems. C# is an object-oriented programming language created by Microsoft and is mainly used on the Windows .NET framework.

Like other programming languages such as Java, C# can be used to create different programs, mobile applications, desktop applications, websites and games. There are mainly three areas in which C# is used:

Windows Applications

With the .NET Framework, C# is used to create Windows applications using Windows Forms or WPF. C# was created by Microsoft, so it is easy to understand why C# is mainly used for Windows applications.


C# is one of the best programming languages for creating games. This language is widely used to create fan-favourite games like Rimworld on the Unity game engine. Unity is the most popular game engine on the market today.

C# for website development

C# is also used to develop professional dynamic websites on the .NET framework. So even if you learn C# to create games, you can still use it to create websites as well.

Advantages of C# Programming

C# is easy to learn

C# is an easy language to learn compared to other difficult languages. Thanks to its simplicity and user-friendly syntax, C# is perfect for beginners. This language is a great first step in the field and offers budding developers a comfortable way to learn about programming without getting discouraged or overwhelmed.

C# is object-oriented

C# is fully object-oriented programming, which is not the case with many other programming languages. Object-oriented programming ensures efficiency, flexibility and organization of code, and also avoids repetitiveness. Some developers who are not familiar with OOP may feel a little reluctant to choose a new language that places such importance on it, but don't worry... Object-Oriented Programming For Absolute Beginners in C#! isn’t all that difficult.

C# supports parallel and asynchronous programming

Sometimes, when we develop an application, we may need to run several tasks on different threads so that we don't waste time waiting for a task to finish, such as reading a text file from a database. Unlike other programming languages, C# supports parallel and asynchronous programming.

How can you learn C#?

There are multiple resources online to master C# and start a career as a software developer, Complete C# Masterclass is a good course for beginners. However, there are multiple free courses available on YouTube, for example, IAmTimCorey - YouTube is a good channel for both beginners, and intermediate and advanced C# developers. If you like reading articles, I wrote a whole article in which I try to explain the most important concepts that you need to know to start your journey in the C# language: Learn C# from scratch for absolute beginners. Then, if you are already familiar with C# syntax and want to dive in object-oriented programming, you can follow have a loog on my previous blog post: Learn object oriented programming in C# from scratch!
