Introduction

Example of a simple C# program:

1
Console.WriteLine("Hello, World!");
Line 1, Char 1

Key characteristics of C#:

• Object-oriented - C# fully supports the object-oriented programming (OOP) paradigm, which makes programs more structured, modular, and easy to maintain.
• Cross-platform - allows programs written in C# to run on various operating systems, including Windows, Linux, and macOS.
• Strong typing - C# is a statically typed language. All variable data types must be defined at compile time, which helps avoid many errors during development.
• Garbage collection - C# uses automatic garbage collection, which frees memory from unused objects and prevents memory leaks.
• Multicore and asynchronous work - C# supports multithreaded programming and asynchronous operations, which is important for creating high-performance applications.
• LINQ (Language Integrated Query) - A powerful tool for querying data collections directly in code. LINQ lets you write SQL-like queries for working with arrays, lists, databases, and other data sources.
• Type safety and exceptions - C# provides a high level of type safety, which prevents errors related to incorrect data handling. It also has a robust exception handling system for managing errors at runtime.

Areas where C# is used

• Web development
• Desktop application development
• Mobile applications
• Game industry
