== C Sharp ==

'''C Sharp''' (often written as '''C#''') is a general-purpose, multi-paradigm programming language developed by [[Microsoft]] as part of its [[.NET]] initiative. It was designed by [[Anders Hejlsberg]] and first released in 2000. C# is known for its strong typing, component-oriented design, and support for object-oriented, functional, and imperative programming styles. It is one of the primary languages used for developing Windows applications, web services, and games (via [[Unity (game engine)|Unity]]).

== History ==

C# was first announced at the 2000 Professional Developers Conference (PDC) as a language targeting the .NET Framework. Its design was influenced by [[C++]], [[Java (programming language)|Java]], and [[Delphi (programming language)|Delphi]]. The language underwent several revisions: C# 2.0 introduced generics and nullable value types; C# 3.0 added Language Integrated Query ([[LINQ]]); C# 4.0 brought dynamic binding; C# 5.0 introduced async/await patterns; and later versions (C# 6.0 and beyond) have continued to add features such as pattern matching, nullable reference types, and records. The language is standardized by ECMA (ECMA-334) and ISO (ISO/IEC 23270).

== Features ==

C# provides a comprehensive set of features including:

* Automatic garbage collection and memory management
* Type safety and strong type inference
* Properties, events, and delegates
* Language Integrated Query (LINQ) for data manipulation
* Asynchronous programming support via the async/await keywords
* Pattern matching and switch expressions
* Nullable value types (int?, bool?) and nullable reference types (C# 8.0+)
* Records and positional records (C# 9.0, 10.0) for immutable data
* Interoperability with native code through P/Invoke and COM

C# is commonly used with the [[.NET Framework]] and [[.NET Core]] (now unified as .NET 5+). It also runs on other platforms via [[Mono (software)|Mono]] and [[Xamarin]].

== Usage ==

C# is widely employed in enterprise software, web applications ([[ASP.NET]]), desktop applications ([[Windows Forms]], [[WPF]]), mobile applications ([[Xamarin]]), and game development ([[Unity (game engine)|Unity]]). It is also used in cloud services ([[Azure Functions]]) and backend services with [[ASP.NET Core]].
