C# (pronounced "C Sharp") is a modern, object-oriented programming language developed by Microsoft. It's known for its simplicity, versatility, and powerful features. C# is widely used in game development, web applications, and Windows applications. It is the principal language of the .NET framework, which provides a large library of pre-coded solutions to common programming problems and a virtual machine that manages the execution of programs written specifically for the framework.
In this tutorial, you will be introduced to the basics of C# programming, including variables, data types, operators, control structures, and loops. As you advance, you'll explore object-oriented programming concepts, error handling, and file I/O, among others. By the end of this tutorial, you'll have a solid foundation to tackle real-world projects and further explore advanced C# concepts.
