What C# is used for
C# is the primary language of the Microsoft .NET ecosystem, used for Windows desktop apps, enterprise back-ends (ASP.NET), and games. The Unity engine makes it one of the most popular languages for game development.
Notable software: countless Unity games, Windows business applications, and Microsoft services built on ASP.NET.
About C#
C# is a multi-paradigm (object-oriented) programming language. It is a statically typed and garbage-collected language that compiles to bytecode that runs on a virtual machine. It supports object-oriented, imperative, and functional programming. Compiling to bytecode for a virtual machine is the same model the JVM and .NET use: the VM, not the CPU, interprets or JIT-compiles the bytecode.
C# first appeared in 2000 and was designed by Microsoft, Anders Hejlsberg, and Mads Torgersen at Microsoft. Today C# is one of the most widely used programming languages in the world.
C# in the language family tree
C# drew on ideas from Java, C++, Delphi, and Eiffel and went on to influence TypeScript, Dart, Vala, and Q#.
