C# Functions: Writing, Debugging, and Reliable Unit Testing

Writing reliable code requires more than just knowing the syntax; it demands strong skills in structured programming, error identification, and verification. This course teaches you how to build the fundamental building blocks of C#—functions (methods)—and equips you with essential debugging and testing skills used by professional developers. What you'll learn: * Understand how to define C# methods, including static vs. instance methods, parameters, and return types. * Apply modern C# syntax features like expression-bodied members for concise function definitions. * Practice effective debugging using breakpoints, variable inspection, and step-through execution to isolate errors. * Master exception handling within functions to manage runtime errors gracefully and prevent crashes. * Configure a basic unit testing environment and write foundational tests for function validation. * Design methods following best practices for readability, maintainability, and single responsibility. We start with core function syntax and structure, move into practical techniques for debugging code flow, and finish by introducing the essential concepts of automated unit testing. This course is designed for beginners who have basic C# knowledge (variables, loops) and are ready to learn how to structure their code using functions and ensure its quality. No prior experience with debugging or testing frameworks is required. Gain the confidence to write professional, error-resistant C# code.
