C# vs Golang: Difference and Similarities

Updated: Jun 8, 2022

What is C#?

C# is a modern, object-oriented programming language. Microsoft's Anders Hejlsberg and his team developed the program, which was a .Net initiative. The European Computer Manufacturers Association (ECMA) and International Standards Organization (ISO) approved the programming language.

C# Pros

  • It runs atop the .Net framework, which provides many libraries with classes for common tasks like displaying a window, editing files, connecting to the internet, etc. This differs from many other languages because, with C#, you don't need to pick from a handful of libraries for small tasks you want to perform.

  • C# is a well-engineered language because everything has its purpose while nothing is non-essential.

  • C# is an awesome independent development environment for windows.

  • It serves as a great introduction to object-oriented programming because it accommodates the most common OOP features like classes, methods, and fields. It also supports features not found in other languages like events, properties, and static classes.

  • Despite being primarily object-oriented, C# supports features mostly found in functional languages. These features include lambdas, delegates, and anonymous classes.

  • It is a good IDE for cross-platform development.

  • It is the best language for Windows programs. Its .Net framework has everything needed to build great apps without resorting to Win32 API or downloading thousands of libraries.

  • With C#, you can combine high and low-level programming. It allows you to code at a high level without being bothered about pointers and memory management. You can switch to a lower level of programming with direct memory management and pointer manipulation when you want.

  • C# is in very high demand in the industry and is regularly updated. It is versatile, easy to read and write, and has excellent tooling support.

  • Many platforms support C#, including Windows, Linux, OS, Apple, Android, and many more.

  • C# is a truly universal programming language with .Net core, which supports desktop, mobile, and web apps.

  • It has a lot of synthetic sugar, making it easier to understand and write code.

  • It has a large community of programmers.

  • There are multiple vacancies for C# programmers worldwide.

C# Cons

  • It has a Bad GUI x-platform.

  • It is less flexible because it depends on the .Net framework.

  • It has a complex syntax

  • Beginners may struggle with its large library and ecosystem.

What is Golang?

Golang is a Google-designed open-source, compiled, and statically written programming language. The names Go and Golang usually confuses people. However, there shouldn't be any confusion because Golang is another name for Go, the programming language's official name.

Golang Pros

  • It is a simple, scalable, multithreaded, and concurrent programming language.

  • It has a simplified C-like syntax that is easy to read and write.

  • It has API documentation that is rich in content and easy to memorize.

  • It promotes programming in a specific conversational style that is less confusing for programmers.

  • It has a built-in unit testing feature that tests functions in codes.

  • It has tools that help full-stack developers automatically format codes for their entire software project.

  • It is easy to install and configure. Also, it is easy to compile the software.

  • It is great for building networking services.

  • It demonstrates a unique, simple concept to object-oriented programming.

  • It generates API documentation for installed packages automatically.

  • It supports modules in the form of packages.

  • It allows source code to be split into multiple files.

  • It allows multiple variables to be assigned on a single line.

Golang Cons

  • Performance may slow down due to indirect calls and garbage collection.

  • The implementation of interfaces is hard to understand.

  • It has no forms designer.

  • It is easy to shadow variables.

Similarities Between C# and Golang

  1. Both platforms leverage a compiler to create native code and provide multi-platform support.

  2. Both have a robust garbage collection mechanism and support modular programming architectures that call upon modules and assemblies.

Difference Between C# vs Golang



Speed of Coding

C# is slower as it's a complex language that compiles codes to cross-platform binaries

Go complies codes into native binaries, to coding is easier and faster with this language


C# utilizes the .NET framework so it performs well on Windows devices but doesn't work so well on other platforms

Due to the absence of complex codes, efficient compile-time checks, memory management, and error handling, software written in Go has great performance


High scalability due to the ability to hold hundreds of thousands of concurrent users

High scalability due to the ability to execute several separate flows


C# offers the right set of data types and library functions

Go can easily use multiprocessor architecture, accommodates pointers, and has an effective garbage collector feature


Very popular as C# is used for commercial software

Not very popular, as Go is used for systems work mostly


Large community

Community of a moderate size

Talent Pool

Wide as C# is the 8th most used programming language

Limited as Go is only 14th most used programming language

Easy Learning

C# is harder to learn as it's statically typed

Go is easy to learn as its syntax is not vast


High level of security

High level of security

Cost of Development

Depending on the project’s complexity

When to use Go?

Due to Golang's support for concurrency, it is great for handling bottlenecks that inhibit scalability. It has a goroutines feature, which offers concurrency by enabling functions or methods to run concurrently with other functions or methods. Meanwhile, channels, a complimentary feature, links goroutines together. Backend developers enjoy most of Golang's benefits because they can handle heavy requests on the server-side with little memory usage.

When to use C#?

C# continues to be an in-demand programming language. Initially, only Windows developers were interested in it, but it has been upgraded to work across other operating systems like Mac OS, iOS, Android, and Linux. Following the removal of all possible restrictions on C#'s usage after platform code was made available to everyone, the language has developed actively with more people using it. C# has a toolkit that allows developers to solve wide-ranging problems. C#'s power and versatility make it a good language to develop web apps, games, mobile apps for Android and iOS devices, and Windows programs.
