C# (pronounced "C sharp") is a general-purpose, object-oriented programming language that was developed by Microsoft as part of the .NET framework. It was first introduced in 2000 and has since become one of the most popular programming languages, particularly for developing Windows desktop and web applications.
C# is designed to be simple, modern, and type-safe, and is often used in enterprise software development, gaming, and mobile application development. It is a statically typed language, which means that variables must be declared with a specific data type and cannot be changed at runtime. This can help catch errors earlier in the development process and improve the performance of the resulting code.
