What Is The Future Of C#

What is the Future of C#

C# is one of the most popular programming languages in the world. C# is also the most versatile programming language among them all. You can build all kind of applications using C# including desktop, web, mobile, IoT, cloud, games, APIs, and libraries. Not only C# can be used to build Windows applications but we can build applications that target Linux, MacOS, iOs, and Android operating systems. On top of that, C# is one of the fastest evolving programming languages among all. With all that background, I can clearly say that the future of C# is bright.
With that said, let’s look at some of the C# language features.

C# is simple, clean, and modern.

C# is one of the easiest programming languages to learn. Most object-oriented programmers will find C# easy to learn and start writing code. C# syntaxes are getting cleaner with every new version and code in the latest version of C#, 9.0, is much cleaner than the previous versions.
C# language supports a majority of modern features you will find in any modern program language.

C# is safe, productive, and fast.

In recent versions, the focus of the language has been on writing safe and efficient code, giving developers more freedom, and writing less code; hence helping them become more productive. With the help of tools like Visual Studio and Visual Studio code and its features such as Intellisense and CodeLens, programmers are able to write code at a faster speed.

C# is open source.

C# is not just for Windows. C# is not just for Microsoft. C# language and the compiler are open source. While the language is managed by Microsoft, the open source community is actively involved in new language enhancements and features.

C# is language for all kinds of software applications.

C# language can be used to build all kinds of software applications targeting desktop, web, mobile, gaming consoles, TVs, Internet of things, and cloud applications.
C# provides WPF, Windows Forms, and UWP technologies to build Windows based desktop applications. ASP.NET is the platform to build web applications. Xamarin can be used to build native mobile apps that target Apple’s iOS and Google’s Android platforms.
C# is cloud native programming language. This means, you can build cloud native apps using C# and .NET platform. Not only can C# be used to build Azure cloud applications, but it can be used to build and deploy applications on any cloud including AWS and Google cloud.

C# is a language for emerging technologies.

C#, as a language, can do a lot more. Today, you can build pretty much any kind of software using C# including data science, AI and machine learning, cloud, enterprise, and report-centric applications. You can also build emerging technology-based applications using C#. Some of the emerging technologies include cloud native, blockchain, mixed-reality, augmented and virtual reality, voice-enabled systems, intelligent chat bots, services and much more.

C# is evolving.

Since its early announcement in the year 2000, C# as a language has come a long way and the good thing is, C# is still fresh and evolving. Each year and each new version, more features are being added and more improvements are being made.

C# language versions and features.

Now, we have just seen some of the key features of C# language, let’s look at some of the language specific features and their release dates.
The following table summarizes C# language versions and features.

Disposable ref structs
C# 9.0
Record types, Structural Equality & Referential Equality, Using Records and the With-expression, Target-typed new-expressions, Default in deconstruction, Relax ordering of ref and partial modifiers, Parameter null-checking, Skip locals init, Lambda discard parameters, Attributes on local functions, Native Ints, Function pointers
As you can see from the above table, C# as a programming language is not only advanced but it is evolving. As technology evolves, C# will evolve as well to support new emerging technologies.
Hence, the future of C# is very bright.
