Comprehensive C# Tutorial

Introduction

This tutorial provides a structured guide to C#, covering fundamental and advanced concepts suitable for both beginners and experienced programmers. We'll explore core features, language constructs, and best practices.

What is C#?

C# (pronounced "C-Sharp") is a versatile, object-oriented programming language developed by Microsoft. It runs on the .NET framework and is designed for building a wide variety of applications, including:

  • Windows applications
  • Web applications
  • Distributed applications
  • Web services
  • Database applications

C# is standardized by ECMA and ISO and is designed for the Common Language Infrastructure (CLI).

Simple C# Example
