C# (pronounced C Sharp) is one of the most popular and powerful programming languages used in modern software development. Created by Microsoft, C# is widely used for building web applications, desktop applications, games, mobile apps, and enterprise-level software. If you're aiming to become a successful .NET developer, learning C# is the first and most crucial step.
This C# Tutorial is designed to help beginners and aspiring developers understand what C# is, why it is so powerful, and how it forms the core of the .NET development ecosystem. Inspired by the clear and practical teaching approach of platforms like Tpoint Tech, this blog will guide you from the fundamentals to the advanced concepts every .NET developer should know — all without overwhelming technical complexity.
What is C#?
C# is an object-oriented, type-safe, and structured programming language developed by Microsoft. It was created to bring the power of C++ and the simplicity of Visual Basic together while offering modern capabilities such as security, simplicity, and flexibility.
C# runs on the .NET framework and the newer .NET Core / .NET 5+ (now simply called .NET). This means applications written in C# can run on Windows, Linux, macOS, mobile devices, and even gaming consoles.
