C# Fundamentals

C# (pronounced "C sharp") is a modern, object-oriented programming language developed by Microsoft. It's used for a wide range of applications, including desktop applications, web applications, mobile apps, and games.

Key Concepts

Here are some fundamental concepts in C#:

• Object-Oriented Programming (OOP): C# is built around the principles of OOP, including encapsulation, inheritance, and polymorphism.
• .NET Framework: C# runs on the .NET framework, a comprehensive development platform.
• Strongly Typed: C# is a strongly typed language, meaning that variable types are strictly enforced, helping to catch errors early in the development process.
• Garbage Collection: C# uses automatic garbage collection, which simplifies memory management.
• LINQ (Language Integrated Query): LINQ allows you to query data from various sources (databases, XML, etc.) using a consistent syntax.

Example Code

                
                    using System;

                    public class Program
                    {
                        public static void Main(string[] args)
                        {
                            Console.WriteLine("Hello, C#!");
                            int x = 10;
                            int y = 5;
                            int sum = x + y;
                            Console.WriteLine($"The sum of {x} and {y} is: {sum}");
                        }
                    }
