C#

C# Training (pronounced “C sharp”) is a programming language developed by Microsoft in the early 20th century as part of the .NET platform. C# is a high-level, object-oriented language designed for building a variety of applications for Windows, web, and mobile platforms. C# is similar in syntax to other C-style languages such as C++ and Java, but also includes features such as garbage collection and a simplified type system. It also supports advanced features such as asynchronous programming, Language Integrated Query (LINQ), and functional programming concepts such as lambda expressions. 

C# is widely used to develop various applications, including desktop applications, web applications, games, and mobile applications. It is also used for developing Windows services, server applications, and cloud services. The language is fully supported in the Microsoft Visual Studio IDE, which provides a wide range of tools and resources for developing C# applications. 

 Designed C# programming

The C# programming language was designed by Anders Hejlsberg of Microsoft in 2000 and was later approved as an international standard by Emma (ECMA-334) in 2002 and ISO/IEC (ISO/IEC 23270) in 2003. Microsoft introduced C# along with the .NET Framework and Visual Studio, both of which were closed source. At the time, Microsoft did not have any open-source products. Four years later, in 2004, he started a free and open-source project called Mono, which provides a cross-platform compiler and runtime environment for the C# programming language. A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the .NET Unified Platform (software framework), all of which support C# and are free, open source, and cross-platform. Mono also joined Microsoft but was not incorporated into NETC#.
