Learn C# Programming

C# (pronounced C-sharp) is a modern, type-safe, object-oriented programming language developed by Microsoft as part of the .NET platform. First released in 2000, C# has evolved through many versions and is today one of the most popular languages in the world for building:
- Web applications with ASP.NET Core
- Desktop apps with WPF and WinForms
- Cross-platform mobile apps with MAUI / Xamarin
- Game development with Unity
- Cloud & microservices on Azure
These tutorials cover everything from your first "Hello World" to advanced design patterns — suitable for complete beginners and developers moving from another language.
