Why learn C#?

C# is the backbone of modern software development, powering desktop applications, web services, cloud computing, and game development with Unity.

Mastering C# isn’t just about learning syntax—it’s about writing efficient, maintainable, and professional-grade code. That’s exactly what this course will teach you.

What makes this course different?

• We go beyond syntax. You'll learn why all the things we learn are needed and how to use them right.
• We emphasize clean code and good design principles from the start.
• Design patterns will be demonstrated in practice, not just as abstract concepts that seem impossible to apply in real-world challenges.
• Refactoring will be something we practice all the time.
• You'll gain hands-on experience through implementing various projects, from processing API data to analyzing PDF files.
• You'll learn how things work under the hood, and thanks to that, you will gain an in-depth understanding of C#.
• You'll master asynchrony, multithreading, and performance tuning.
• You'll practice unit testing with NUnit and Moq to build reliable software.
