This course now features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. This course is designed to take you from a complete beginner to understanding the fundamentals of C# and .NET. By the end of this course, you'll have a solid foundation in C# programming, from setting up your development environment to writing, debugging, and troubleshooting your code. You will begin by exploring what C# is, setting up Visual Studio Code, and diving into your first program. As you progress, you'll learn how to work with variables, arrays, and different data types in C#, such as text, numbers, and booleans. Understanding operators in C# will be your next step, where you’ll master the basic types, including unary, mathematical, assignment, comparison, and conditional operators. In the following sections, you'll dive deeper into control flow with selection statements (if, if-else, switch) and iterative statements (while, do-while, for, foreach). You'll practice these concepts with hands-on demos and assignments that will help you build a strong understanding of how C# works in different scenarios. This course is perfect for absolute beginners who have no prior programming experience. It’s also suitable for those who want to learn the basics of C# to further develop skills for more advanced programming topics. There are no prerequisites, and the course is beginner-friendly with step-by-step tutorials.
