freeCodeCamp's Full C# Course for Beginners teaches C# syntax, object-oriented programming, and working with the .NET ecosystem in about 4 hours. The entire course is free on freeCodeCamp.org. After finishing, you understand C# fundamentals and can write object-oriented programs. C# runs on Windows, Linux, and Mac through .NET (formerly .NET Core). It's similar to Java in style but with modern language features and tight integration with Windows/Azure. The main limitation: 4 hours is an introduction. You'll need more practice and depth in .NET to build real applications.
C# is used by 25.4% of professional developers and is the language of .NET and Windows development (source: Stack Overflow Developer Survey 2024).
