Free C# Courses

C# is Microsoft's answer to Java, and it runs most of the .NET world: business software, Windows apps, and a big share of professional game development through Unity. It sits in a practical middle ground, higher-level and more forgiving than C++, but faster and more structured than a scripting language. The free path here is unusually clean. Microsoft Learn's C# for Beginners is interactive and ends with a certificate, and freeCodeCamp's 8-hour course covers the same ground in video form if you'd rather watch first. When the basics hold, Microsoft's Build .NET applications with C# course moves you into writing real programs with the framework you'll use on the job. C# is a strong pick if you're aiming at enterprise development or Unity games; it shows up less in startups and data work, so match it to where you actually want to end up.
