C# (pronounced „C-sharp“) is a modern, object-oriented programming language developed by Microsoft. It is widely used for developing Windows desktop applications, Windows phone apps, and games for the Xbox and Windows platforms. C# is also commonly used for developing enterprise applications, web applications, and web services. C# is part of the .NET framework, which provides a large library of pre-built code that can be used to perform common tasks, such as reading and writing files, connecting to databases, and working with the Internet. This framework also provides a common runtime environment, which allows C# code to run on multiple platforms, including Windows, Linux and MacOS. C# is a statically-typed language, which means that variables must be declared with a specific data type, such as int or string. It also supports features such as object-oriented programming, automatic memory management, and exception handling. C# also supports modern features like async/await, Linq and Lambdas. C# is a powerful and versatile language, and it’s widely used in industry, especially in the development of enterprise software and games. It’s also a popular choice for beginners to learn programming as it’s relatively easy to learn and understand, and it has a large and active community.
