The language, along with the .NET framework, can also be used to develop applications for systems running Linux, macOS, iOS or Android, although C# is used primarily to develop Windows applications. It will take less time if you are already familiar with another programming language. With that said, the amount of time it takes to learn C# depends on the time you can devote to learning and practicing it. If you hit a wall while trying to self-study, you can always enroll in an online course or a coding bootcamp. TIOBE’s index shows Python as the most popular and in-demand programming language.

C# combines the computational power of C++ and the ease of Visual Basic, Microsoft’s event-driven programming language and environment. C# gets its foundation from C++, has features similar to Java and applications across many areas in software development. Developers can use C# in many areas of software development including game and app development. The CLR runs the code and provides services that enable and enhance application development and cross-platform designs. It also offers high-level support for programming languages such as C#, F# and Visual Basic.

Methods and functions

The data used to compile this index is based on how often people search for a tutorial on different programming languages in Google. Although C#’s syntax is more consistent and logical than C++, there’s still plenty to learn. C# is a complex language, and mastering it may take more time than simpler languages such as Python. This means users do need to learn a substantial How To Build a Strong Engineering Culture Trio Developers amount of code to create advanced programs, which may be off-putting for some new users. It’s a high-level language, relatively easy to read, with many of the most complex tasks abstracted away, so the programmer doesn’t have to worry about them. Memory management, for example, is removed from the user’s responsibility and handled by .NET’s garbage collection scheme.

Unity is a framework for C# that is specifically designed for creating video games. Today, Unity is the most widely-used game engine, with over a third of top-selling games having been built with it. Unity is also currently used for the development of most VR games. Approximately 90% of all Samsung Gear and 53% of all Oculus Rift games have been developed with Unity. C# is one of the most widely used languages in the world, which means that there are many C# developers ready to lend you a hand with it. Being a Microsoft product, C# has the support of the tech giant, which translates into expert help, additional resources, and frequent updates.

There is a place for everything and everything is in its place. Judging by the quick rise to popularity and the positive response from both new and seasoned developers, it’s safe to say that goal has been achieved. As we often tell our students, a university education will always give you a broader picture and teach you the underlying concepts of programming. However, studying Computer Science doesn’t guarantee that you’ll know how to code upon graduation. One of the best ways to learn C# is directly from Microsoft themselves.

The language is intended to be a simple, modern, general-purpose, object-oriented programming language. Microsoft provides extensive documentation for C# and .NET, including interactive tutorials, video series, and problem explanation. A large part of documentation is devoted to the .NET resources like the common type system, compilers, and asynchronous programming capabilities with C#.

Categories of data types

C# has a built-in garbage collector, it allows for using code interfaces, and is object-oriented by design. Being powerful, flexible, and well-supported has meant C# has quickly become one of the most popular programming languages available. Today, it is the 4th most popular programming language, with approximately 31% of all developers using it regularly.

Unity is also used for VR, with 90% of all Samsung Gear and 53% of all Oculus Rift VR games developed using Unity. C# has embraced object-oriented programming in such a way that it might be the language that better leverages it. In fact, being object-oriented allows C# to be highly efficient and extremely flexible, all of which makes development easier and less resource-intensive. What’s more, even though C# has had many years in the market, the number of developers using it doesn’t seem to be decreasing. The reason for this is that companies hiring C# engineers want professionals who can work in multiple projects, and the language’s versatility precisely provides that ability. As a part of the .NET platform, C# is a natural fit for building dynamic websites and applications.

Interoperability means that C# code can interact with applications written in compatible languages such as C++, F#, Visual Basic, and Windows PowerShell. This allows developers to use different languages in a single assembly. A runtime is used in .NET applications to translate C# code into machine instructions on any of the supported OS.

To better understand C# programming, we’ll first need to address .NET, the framework that goes hand in hand with this programming language. Developed by Microsoft, the .NET framework contains a huge number of class libraries (pre-written code) to help developers create applications faster and more efficiently. Because both C# and .NET are products of Microsoft, it’s not very common to see one mentioned without the other. There are, however, a few other frameworks that are used with C#, such as Unity. C# is a modern object-oriented programming language developed in 2000 by Anders Hejlsberg at Microsoft as a rival to Java .

Advantages of C#

This has been a conscious decision based on the issues of scalability and versionability. C# offers Java-like synchronized method calls, via the attribute [MethodImpl(MethodImplOptions.Synchronized)], and has support for mutually-exclusive locks via the keyword lock. C# supports strongly, implicitly typed variable declarations with the keyword var, and implicitly typed arrays with the keyword new[] followed by a collection initializer. Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation. As of November 2022, the most recent stable version of the language is C# 11.0, which was released in 2022 in .NET 7.0.

  • They simply work well together, due to being developed by Microsoft.
  • That said, as a first programming language, C# isn’t the easiest one to learn but it’s definitely worth it, especially if you already have coding experience.
  • Uses of C# has various language constructs which again scores over Java.
  • If you are interested in pursuing a career as a C# developer, keep reading.
  • The resources within the BCL let you focus on specific business problems rather than how to convert a string to uppercase or deal with type conversion.

Yield – Yield and return yield are used in C# to perform custom and stateful iterations without an explicit extra class and without a need to create any temporary collection. The as a keyword in C# attempts to safe-cast an object to a type, and if it can’t it returns null. Built In’s expert contributor network publishes thoughtful, solutions-oriented stories written by innovative tech professionals.

Object-oriented programming

Libraries in .NET are often updated and there are thousands of resources you need to learn before getting your job in C# programming. Not to mention you’ll have to work with multiple runtimes if you want to develop cross-platform applications as C# or .NET apps don’t work on Linux or macOS natively. The Base Class Library, or BCL, is an extensive code library of common functions that have been developed, tested, and provided free of charge by Microsoft. The resources within the BCL let you focus on specific business problems rather than how to convert a string to uppercase or deal with type conversion. When you use C# effectively, you’ll enjoy a faster development timeline and simplified solutions.

C# language is considered a high-level language because its syntax resembles human language. In other words, it has a high level of abstraction from a machine code, which is why we need to compile the code written in C# for the hardware to understand its commands. The set of tools and libraries is created to develop C# applications or write new libraries. With the acquisition of Xamarin and its native Mono Runtime in 2016, .NET and C# got cross-platform capabilities for the first time. Because of this, C# applications can be coded once and launched on any platform, including Web apps, Windows, macOS, Linux, Android, and iOS.

And that’s without considering the many built-in features that are very simple to use. What’s more, any engineer who already knows C++ or Java will feel right at home when first using C#, as these languages share many of the same features and overall approach to programming. Not any more……ECMA and MONO project is evidence that says in the favor of applications of C#.

This is a never-ending discussion that always goes on in the developer’s community. This brings our decision which gives us an understanding of the right language and platform to choose for the underlying product development. No language is good or bad it all depends upon the exact need and purpose. There are countless things to consider before the development actually starts, FACEBOOK are stuck with PHP they have no options to choose from. Even if they wanted to move or switch to ASP.NET they simply cannot.

In C#, memory address pointers can only be used within blocks specifically marked as unsafe, and programs with unsafe code need appropriate permissions to run. An unsafe pointer can point to an instance of an ‘unmanaged’ value type that does not contain any references to garbage-collected objects, array, string, or a block of stack-allocated memory. Code that is not marked as unsafe can still store and manipulate pointers through the System.IntPtr type, but it cannot dereference them.

And, owing to the latest version of .NET, C# can now be used to write Linux and macOS applications as well. Software Development Services Accelerate your tech projects with outsourced development. What really makes C# stand out is the large community behind the language. There are more than 100 active contributors in the C# language design repository. These updates help the language reflect the modern-day development style and needs. Provides an unsafe context that enables developers to incorporate unverifiable code into their applications.
