You'll be introduced to code smells at the statement, method, and class levels in C# applications. You'll also learn about the process of refactoring your code to eliminate design flaws and improve its maintainability. Finally, you'll learn how to apply dozens of specific refactorings to common, known problems in C# applications. When you're finished with this course, you'll have the skills and knowledge needed to identify code quality problems and correct them with quick and reliable refactoring techniques.
