Description
C# is a versatile, object-oriented programming language developed by Microsoft. It's primarily used for building Windows desktop applications and games, but it's also used in web and mobile development. C# allows developers to create efficient, robust applications with less code due to its simplified syntax. It supports concepts like polymorphism, inheritance, and encapsulation, which are fundamental to object-oriented programming. Additionally, C# includes advanced features like asynchronous programming and LINQ (Language Integrated Query), making it easier to handle complex tasks. Understanding C# requires knowledge of its syntax, data types, control flow, classes, interfaces, and more.
