Sometimes you want a language that does it all. When that’s the case, you need a language like C#. Considered to be a rival to Java, Microsoft developed C# in 2000.

You can create a little bit of everything with C#. But its main uses are for Windows desktop applications and game development in Unity.

At Trio, we not only deliver top-tier content and insights in software development but also offer the finest South American developers for outsourcing. Explore our talented Argentinean developers, Colombian developers, and Brazilian developers to elevate your projects today.

What Is C#?

C# is a general-purpose programming language with a diverse range of features from strong typing to lexical scoping. It’s widely used for developing web applications, web services, and desktop applications.

What’s more, C# is multi-paradigm, declarative, functional, generic, component-oriented. Let’s run through some basic definitions.

Strong typing refers to languages where the variable type can not change. As opposed to weak typing, strong typing can prevent run-time errors later on.

In lexical scoping, the scope of a function must be defined. This establishes whether a variable or other program element can be referenced outside the function it was written in.

Object-oriented, as you probably know, means C# allows developers to manipulate objects in an intuitive, class-based fashion.

Multi-paradigm encompasses much of the previously stated characteristics of C#. Programming languages that support more than one programming paradigm are multi-paradigms.

Imperative is a programming paradigm denoting that a C# statement can change the state of a program. It entails detailing the steps developers want the machine to take in order to solve a problem.

Declarative programming is its contrast, but this can be used in C# as well. In declarative programming, developers express what they want without delineating a step-by-step procedure.

Functional programming occurs when functions are used as the main utility for writing a program.

Generic programming languages permit code to be written with algorithms that have to-be-specified-later variable types.

Component-oriented programming is just as useful as object-oriented programming. It works by inserting new and pre-existing components into your project.

These various programming disciplines make C# extremely modern and flexible. This explains why developers use C# to develop embedded systems, desktop applications, web applications, and games.

Microsoft’s .NET is also a frequent alliance to C#. The .NET framework is a free, open-source platform that carries tools to help developers build virtually any app in C#.

What Is a C# Developer?

A C# developer can have a variety of roles depending on what your business needs. At the very least, C# developers know how to write and maintain C# code.

C# developers might build applications to work on desktop computers or work closely with the back-end processes needed for web applications.

These developers should have a great intuition for developing using the object-oriented programming paradigm, as well as any of the other programming paradigms that fall under C#.

Why Use C#?

Given that C# is such a wide-ranging language, it’s important that you understand what exactly C# can do for you at every junction. As it stands, games, web apps and services, and desktop applications are the primary development uses for C#.


Where games are concerned, Unity is always part of the conversation. Unity is a game engine for building 2D and 3D games that relies on .NET and the C# programming language.

Though not as popular, C# game developers can also opt to use MonoGame or CRYENGINE to build games.

MonoGame is an open-source game development platform built with .NET that supports both C# and F#. CRYENGINE is a framework that allows developers to use .NET and C# to develop games, much like Unity.

Web Apps & Services

ASP.NET is a Microsoft framework for building modern, scalable web apps with built-in model-view-controller (MVC) support. In it, you can build apps with real-time bi-directional communication between server and client.

MVC is a prized design pattern amongst web developers. The pattern distinguishes concerns structurally for the data, user interface (UI), and inputs for a web application.

You also have the ability to develop REST APIs that can help your app communicate with other clients from browsers to mobile devices. Developers can use a microservice architectural approach to build web apps as well in ASP.NET.

Blazor is a feature provided in ASP.NET for building interactive web UIs. And Razor is a specific programming syntax used for creating dynamic web content with HTML and C#.

Desktop Applications

Windows Presentation Foundation (WPF) is a UI framework for creating desktop applications. WPF apps are written in C#. Today, web applications are much more popular than desktop applications.

But there are still plenty of relevant applications that you know and use today that are written in C#. A few examples are Quickbooks, just about every Unity game including popular titles like Hearthstone and Monument Valley, and of course, the whole Microsoft Office suite.

Advantages of Using C#

C# has quickly risen through the ranks of programming languages more long-standing and pointed. It hasn’t surpassed Java but C# still places in the top ten when compared to other languages. What makes C# so appealing?


If you’ve never heard of C# but still the name seems familiar, then perhaps you’ve heard of C and C++. Before C#, C and C++ were the top picks for a middle-level language to efficiently build software that could interact close to hardware systems, like desktop applications, for instance.

C# has the advantage of being a newer language. Though it is based on C++ and also syntactically similar, it has many useful upgrades.

Some of these upgrades include rapid development, new data types, and a powerful forms engine – courtesy of the .NET framework.


Type safety and memory safety are two provisions of C#, both of which C++ lacks.

As far as type safety, this means you can not use uninitialized variables, leading to fewer errors down the line.

Memory safety is a property of programming languages that use some sort of methodology – in most cases and in this case, garbage collection – to protect against security vulnerabilities and software bugs.

This is particularly a concern for middle-level and high-level languages that must consider memory allocation when dealing with low-level systems.


Like established, C# has more than a few programming disciplines which you can opt into at will. Naturally, the most favored programming paradigm among them all is the object-oriented paradigm.

Object-oriented programming has always been advantageous to coders as it permits them to structure programs intuitively and with real-world constructs.

Ease of Use

Code readability and high-level abstraction make C# easy to learn. However, it is still complex enough to provide low-level access.


In C#, you write XML comments. This is a bit more exciting than your regular hash symbol and forward slash. It means that developers can export their comments into well-structured documentation.


One feature of C# is cross-language interoperability. Simply put, any other language on the .NET platform can work together with C#. Feel free to use F# or Visual Basic while you enjoy all the qualities of C#.

Reasons to Hire a C# Developer

C# developers can do many things for your business. Whether you want a desktop or web application, or even to build a game, C# could be the right language for your business.

With that, it doesn’t matter so much what you’re developing in C#, but it does matter that you have qualified developers to help you reach your goals.

How to Hire a C# Developer

Being at a relative peak for flexibility and modernity amongst popular programming languages, C# has grown to major popularity with over 30% of developers opting to use the language.

This is to say, C# is very much in high demand. You’ll have a large pool of applicants to choose from if you’re looking to hire C# developers.

How do you hire a C# developer?

For those who wish to take the high road and hire C# developers on their own, we’re still here to help.

Hiring a developer on your own is a very focused and hands-on process that requires considerable knowledge about software development in general.

The last thing you want to do is trust your hiring process to someone with no technical ability. If you are a non-technical manager looking to learn a thing or two, we have a great resource here for you to learn more about the hiring process in detail.

Otherwise, we’d recommend you contact Trio for consulting and developer allocation.

What should you look for in a C# developer?

C# developers at a professional level should have the following qualities:

  • High-level familiarity with the .NET framework
  • Proficiency with one of the many programming paradigms supplied in C#, especially object-oriented programming
  • For web developers, a background in web technologies like JavaScript, HTML, and CSS
  • For developers building desktop applications, a comprehension of software development at a low-level

How much do developers cost in the U.S.?

ZipRecruiter data records the average salary for C# developers in the United States at $103,699 per year. In general, salaries can range as low as $88,000 and as high as $117,500.

How much do developers cost in South America?

Due to economic differences between the United States and South America as a whole, the cost of offshoring software development is significantly lower than hiring full-time with U.S talent. For Senior C# Developers in South America, the average salary is currently around $100,000 whereas a mid-level developer costs around $76,000.

How much do developers cost in Ukraine / Eastern Europe?

Eastern Europe shares very similar rates to South America, again due to the economic differences. When looking at salaries in Eastern Europe, data shows that a Senior C# Developer costs around $100,000 on average.

Hourly Rates for Developers

Another way to look at developer costs is through hourly rates. While salaries are good to understand for hiring developers for full-time and long-term, you might just need a developer for a period of 3-6 months or 6-12 months. In these types of situations, it’s best to calculate your costs based on the hourly rates of a developer.

Below is a table that lists the various hourly rates of developers in different locations based on their job title.
