How Many C# Developers Are There in the World?

Learn how many C# (C sharp) developers are there. The popularity of the C# programming language and what kind of IT products it can be used for.


Created by Microsoft two decades ago, C# continues to be one of the most widely used programming languages.

C# (pronounced "See Sharp") is a modern, object-oriented, and type-safe programming language that enables developers to build many types of secure and robust applications that run in .NET. From the ground up, C# was designed with simplicity and readability in mind. As implied in its name, C# has its roots in the C family of programming languages so it is familiar to C, C++, Java, and JavaScripts programmers.

C# has several features to help developers create strong and durable applications. For example:

  • Garbage collection: Automatically reclaims memory occupied by unreachable unused objects. 
  • Nullable types: Guard against variables that don't refer to allocated objects. 
  • Exception handling: Provides a structured and extensible approach to error detection and recovery. 
  • Lambda expressions: Support functional programming techniques. 
  • Language-Integrated Query (LINQ) syntax: Creates a common pattern for working with data from any source. 
  • Language support for asynchronous operations: Provides syntax for building distributed systems. 

Today, there is no doubt  C# is one of the most popular programming languages. But who exactly is using it?

Who are C# developers?

According to a report by SlashData, the world has more developers than ever with an average of 24.3 million JavaScript developers up to 2021, a quantity that is expected to grow to 27.7 million in 2023 and 28.7 million in 2024. But who exactly is using C# and how many c sharp developers are there? 

C# developers build applications and programs using the .NET framework for use on Windows operating systems. They primarily write code, develop and design user interfaces as well as debug and maintain code for clients. They can be trained as full-stack developers or specialize in either front-end or back-end coding.

Now, according to the last information available, the number of c# developers in the world is around 6,2 million. 

As far as usage, C# is popular for augmented reality/virtual reality (AR/VR) development and desktop development: C# is traditionally popular within the desktop developer community, but it's also the most broadly used language among AR/VR and game developers, largely due to the widespread adoption of the Unity game engine in these areas.

What C# is used for

Being a general-purpose language, C-sharp can be used to create a wide range of programs and applications like mobile apps, desktop apps, web apps, enterprise software, video games, cloud-based services, and more. It is a versatile language you can use almost anywhere and considering its many advantages, it might just be your best choice.

C# can be employed to create almost any kind of app. As a general-purpose language, C# allows developers to build:

  • Console applications
  • Desktop application
  • Web services and applications
  • Mobile applications
  • AI applications
  • Cloud applications
  • IoT applications
  • Reusable libraries 

Popularity of C#

According to HackerRank, roughly one of every five hiring managers (PDF, 2.4 MB) is looking for a developer that can code with C#. There’s no denying that it is one of the most in-demand coding languages for the upcoming years. Here are some reasons why.

Relevant and Simple

Though C# has been around for two decades already, it is one of the most dynamic languages out there. It is used widely in a variety of industries and is quite simple to learn and use. It is a perfect choice for building interoperable, robust, and scalable applications. It is also used in game development, specifically in the Unity engine. The capabilities of C# are quite impressive, which is why it might be a good choice for your project too.


What interoperability means is that you can use parts of code written in different languages and they would still interact with one another. Whenever you hire C# developers to add improvements or new features to your existing applications, you know they’d be able to do it without rewriting the base code.

Regardless of which language was used to code a base app, C# can be used to scale it up and expand its functionality with relative ease.

Rich Libraries

C# offers a rich library of tools that are used to accomplish a variety of goals. Such frameworks as .Net, Newtonsoft, and Cake, to name a few, have been extremely popular among developers thanks to their built-in features that make the development process much faster and easier. Thanks to the number of libraries, C# can be used almost anywhere and accomplish a variety of goals all at once.


C# works perfectly with most devices and operational systems. You can use it to make applications for Windows, iOS, and Android without having to change the code.

Unlike certain languages where you’d have to rewrite large portions of code to fit different platforms, with C#, you don’t need to do that. If you are planning to develop a multi-platform application, hiring a C# development team might just be the right way to go.

Summing up

C# language it is arguably one of the best options to build apps. Its ease of use and ability to speed up development is one of the main advantages of this language, and although some programmers refuse to use C#, considering it too slow, C# is still in high demand in top software companies around the world.
