C#, which is pronounced “C sharp” like the musical note, is an object-oriented programming language. Developed by Dutch software engineer Anders Hejlsberg together with a team of developers at Microsoft, it was created as a hybrid of the languages C++ and C and was designed to improve productivity when developing web applications. C# was released in 2000 as part of the .NET (“dot net”) framework and is used with XML-based Web services.

C# was developed to facilitate the flow and exchange of data and services over the internet and allows programmers to create highly portable applications. The use of C# helps simplify programming when used with Extensible Markup Language (XML) and Simple Object Access Protocol (SOAP). These tools allow the programmer to get access to a programming method or object without writing additional code for every step.

With C#, a programmer can build on already existing code, instead of duplicating it repeatedly. Programmers use C# to make the development of new products easier and less expensive than using traditional, older programming languages. One of the advantages of using C# is its simplified type declarations. C#’s scalability and versioning support, garbage collection, and other features make developing solutions faster and easier, especially for Web services and COM+ services.

C# was submitted to the standards organization Ecma International in 2001 where it was recognized later that year as an international standard. In 2003 it was accepted by the International Standards Organization (ISO). The recognition of C# by the ISO was expected to encourage other organizations to develop their versions of this language.

Compared to the C and C++ languages, C# is considered to be an improved implementation, providing safe default conversions that can be evaluated at runtime. For programmers with prior knowledge of C and C++, learning C# is relatively easy.

The difference between C#, C and C++ is best seen in the code itself. C# is explicitly designed for use in multiple platforms and for use with the Common Language Infrastructure that includes executable code and a runtime environment. This allows the use of different high-level languages on various architectures and platforms.

In summary, C# is a derivative of the C language and is also similar to C++. C# uses the same basic operators as C++, is case sensitive, and has similar or almost identical syntax. Since its release in 2000, C# has become a widely used professional programming language, which many developers find relatively easy to learn and allows faster development of applications.
