CShapr vs Go Technology Comparision

C# and Golang are programming languages with similar features but different implementation patterns. Both languages offer similar benefits, but each has its strengths depending on what you want to use it for. 

 

C# is the older of the two programming languages. Microsoft launched it in 2000, and programmers use it for creating mobile, web, and cloud-native apps. Meanwhile, Google built Go in 2009 as a successor to C. Go can handle Google's large network servers without reducing speed, simplicity, and readability. 

 

Due to C# and Golang's similarities, deciding which of them to use for a particular project may depend on the project's requirements. However, each of them may be more beneficial than the other in some instances. It is important to know each language's strengths and weaknesses to make an informed decision when you have to choose between them. 

 

We’ve already written many articles comparing various technologies such as Go vs Rust. And now it’s time to learn more about C# vs Golang. You will know how they are similar and understand their differences. After reading this article, it will be easier to decide between Golang vs C#.

What is Go?

Golang is a synonym to Go, which 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. 

 

The name, Golang, originated from Go's official website, golang.org. In addition, it is easier to search for Golang than Go on Google. Thus, people searching for information about Go will find it easier using the keyword “Golang.”

What is C#?

C#, pronounced as "C sharp," 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.

Why Should We Compare Them?

Go and C# should be compared because they are similar programming languages. They also have features that satisfy the requirements for software development. Thus, they are both ideal for solving enterprise service problems. 

 

Go and C# use compilers to create native code and can be used across multiple platforms. In addition, their garbage collection mechanism is extensive. They also support modular programming structures that employ modules and assemblies which is very useful.

 

These programming languages have C language origins. C# is C-based and has a similar syntax, while Go is C-inspired and has a similar syntax but with easier readability. 

 

Go and C# have a rich collection of base class libraries and accommodate asynchronous operations. Besides these similarities, the programming languages' performance thresholds are also similar. 

 

Based on these multiple similarities, it is only wise to compare Golang vs C# to know how they outperform each other. Also, it is good to understand their capabilities to know when best to use them. Without comparing them, it won't be easy to know how they differ and what they are best for. 

Main Comparison Areas

In this section, you will see how Go and C# compare in ten different areas. These comparisons will help you to understand these programming languages better. 

Speed of Coding/Easiness of Coding

Go library is created according to the best development standards in the modern world, so it is very simple and easy-to-scale. Go automatically removes unnecessary parentheses, thus developers spend less time typing the code and focus more on the debugging activities afterward.

 

C# is also quite easy and fast to code with, especially when it comes to its newer versions. The language has autocomplete and dynamic typing features which help to detect errors and speed up the entire coding process

 

Verdict: Both

Performance

In terms of coding, Go and C# compile written text into machine code. C# compiles codes to cross-platform binaries. These codes need the .NET Core Runtime to run. It is a complex language but also well-engineered. However, Go compiles codes into native binaries bound to the operating system, making it faster and more efficient to code than C#.

 

In comparing Go vs C# performance levels, you should note that both languages have good performance levels when weighed with other programming languages like Python and Java. However, they differ in strength. 

 

Due to Go's lightweight nature, it excels over C# when it comes to performance. Go has efficient compile-time checks, error handling, and memory management. This is because of the absence of complex codes. The programming language also uses low resource storage, which, combined with static typing, contributes to faster compilation and memory management. Thus, there is a boost in performance despite the presence of a garbage collector and concurrent operations. Unlike C#, which compiles across platforms, Go compiles into the native binary of each machine. 

 

C# utilizes the .Net framework, which determines its performance. The framework powers the programming language's garbage collector and error platform. C# is most optimized on Windows devices and performs exceptionally well on such machines. However, its cross-platform performance is moderate. 

C# is more powerful than Go but slower than it mostly because it has heavier features while Go is lightweight. Go has a simpler language that allows it to run fast, whereas C# excels in specific environments. 

 

Verdict: Go

Scalability

Go runs faster because of its compilation features, which also enhance its ability to execute several separate flows. Go also comes with an in-built concurrency feature. Meanwhile, C# is one of the best programming languages if you are looking for a technology that can hold hundreds of thousands of concurrent users. 

 

Verdict: Both

Golang vs C# Features

Golang's major features are its simplicity, consistency, and concurrency. Thanks to its concurrency, it can use multiprocessor architecture without hassles. Also, Go accommodates pointers, enabling references to be passed to values and records. That way, it is easier to track data. Lastly, Go's garbage collector feature can effectively handle memory leaks. 

 

C# provides a structured approach and has a rich set of library functions and data types. It is a modern programming language that is powerful and simple for creating scalable, robust, and interoperable applications. The object-oriented programming language has a type-safety that improves its security and an interoperability feature that allows it to do almost anything a native C++ app does. It is also scalable, updateable, and component-oriented. 

 

Verdict: Both

Popularity

According to the survey of StackOverflow conducted among over 83 thousand developers in 2021, 27,86% of developers use C# and 9.55% of coders utilize Go.

C# is an in-demand programming language. There are many jobs in companies looking to hire C# developers for new or large enterprise projects. C# has a large scope, meaning that it is possible to specialize in several areas within the programming language and use familiar libraries and tools. Lately, C# has dropped in its popularity ratings, but it continues to grow and is widely regarded in game development. 

 

In terms of job availability, there are more jobs available for C# developers than Go developers. Go is used much more for systems work, while C# is preferred for generic commercial software. C# tends to be more popular than Go, but developers fancy both languages and use them to satisfy different needs.

Verdict: C#

Community

The community support of C# is declining over time. Microsoft has attempted to encourage the activity within the community by releasing open-source ASP.NET Core, however, hasn't helped a lot. On the other hand, C# is widely used by big corporations for commercial product development, so there is plenty of informational resources and quality support that can be located.

 

Go is a relatively new project, thus its community is still very active and excited about the project. There are plenty of open-source libraries and detailed code examples that you can refer to while running into any problems. 

 

Verdict: Go

Talent Pool

According to the 2021 Stack Overflow Developer Survey, C# is the 8th most commonly used programming language, with 27.86% of respondents preferring to use it. Go holds the 14th position, with 9.55% of respondents preferring it as their favorite programming language. Also, 29.81% of professional developers who took part in the survey prefer working with C#, while 10.51% love Go. 

 

Meanwhile, 14.54% of web developers who are not developing with the language expressed an interest to develop with Go, while just 6.54% want to develop with C#. 62.74% of the survey's respondents love Go, while 61.96% love C#. 

 

This data shows that while more people prefer working with C# over Go, more people love Go and want to develop with it than C#. 

 

Verdict: C# (This may change in a few years)

Easiness to Learn/Learning Curve

The syntax of Go is not that vast. Hence learners can quickly get acquainted with its units and functions. Go is procedural and can be a little more rigid and hard for beginners. However, experienced programmers find it easier and use it to complement their knowledge of other languages they already know.

 

On the other hand, C# is statically typed, meaning that you must change variables independently. C# is a perfectly balanced object-oriented programming language, making it easy to start learning. Beginners start with simple and concise instructions before delving gradually into more powerful tools like Linq and lambda expressions. 

 

Verdict: Go

Security

It is difficult to say which is more secure between C# vs Go, even though C# seems to have an edge. In programming languages, security has so much to do with using a language correctly when writing the code. Whatever programming language you use, ensure you keep to the best practices. These include having the latest tech versions for that programming language, scanning code for errors or malicious material, and updating the servers. There are several threats programming languages face. Thus, you need to protect your codes from such threats and encrypt sensitive information to secure your code and environments. It would be best to employ only professional developers to ensure your code's security. 

 

Verdict: Both

Cost of Development

Several factors affect the cost of development, so it is difficult to say which of Golang vs C# costs more to develop. These factors include task complexity, personal hourly rate, management drawbacks, building a team or outsourcing, and much more. You have to consider these and other factors before saying which one costs more. Rather than estimating the cost, it is best to get a quote from a company or consult a professional

 

Verdict: Both

C# vs Go: When to Use 

Due to the programming languages' similarities and the differences in their implementation, knowing when to use either of them is important. Below are what Go and C# are good for.

What Is Go Good For?

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. 

 

Go can be used in applications like distributed network services, cloud-native development, replacements for existing infrastructure, utilities and stand-alone tools, news outlets, media platforms, and on-demand services. 

Examples of services that use Go include on-demand platforms like Uber media platforms like Netflix, YouTube, and SoundCloud.

What Is C# Used For?

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.
