Microsoft's C# for Beginners is a free video course teaching C# fundamentals: syntax, variables, loops, functions, and object-oriented programming. The course is on Microsoft Learn, Microsoft's official learning platform. After finishing, you understand C# and can write simple programs. C# is the language of the .NET ecosystem, used for Windows apps, web development (ASP.NET), game development (Unity), and cloud applications. The main limitation: the course is introductory. For real development, you need a framework (ASP.NET for web, Unity for games).
