The C# programming language was designed by Anders Hejlsberg from Microsoft in 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO / IEC (ISO/IEC 23270 and 20619 [c]) in 2003. Microsoft introduced C# along with .NET Framework and Visual Studio, both of which were closed-source.

A C# application consists of classes and their members. Classes and other types exist in namespaces but can also be nested inside other classes. Main method. Whether it is a console or a graphical interface application, the program must have an entry point of some sort. The entry point of the C# application is the method called Main. There can ...
C# is case sensitive and all C# keywords are in lower cases. Visual Basic and C# share most keywords, with the difference being that the default Visual Basic keywords are the capitalised versions of the C# keywords, e.g. Public vs public, If vs if . A few keywords have very different versions in Visual Basic and C#:
Common Type System. In Microsoft's .NET Framework, the Common Type System ( CTS) is a standard that specifies how type definitions and specific values of types are represented in computer memory. It is intended to allow programs written in different programming languages to easily share information. As used in programming languages, a type can ...
Roslyn (compiler) .NET Compiler Platform, also known by its codename Roslyn, [2] is a set of open-source compilers and code analysis APIs for C# and Visual Basic (VB.NET) languages from Microsoft. [3] The project notably includes self-hosting versions of the C# and VB.NET compilers – compilers written in the languages themselves.
C Sharp 3.0. The programming language C# version 3.0 was released on 19 November 2007 as part of .NET Framework 3.5. It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime.

Generics, or parameterized types, or parametric polymorphism is a .NET 2.0 feature supported by C# and Visual Basic. Unlike C++ templates, .NET parameterized types are instantiated at runtime rather than by the compiler; hence they can be cross-language whereas C++ templates cannot. They support some features not supported directly by C++ ...
