A Hands-on Guide on Common Code Smells in C# and How to Refactor Them using ReSharper

"Any fool can write code that a computer can understand. Good programmers write code that humans can understand." - Martin Fowler

Poorly written code is hard to understand, maintain and test. But what separates poorly written code (aka code that smells) from beautiful code that talks? In this course, Mosh walks you through common code smells found in C# programs and how to refactor them using ReSharper. Refactoring is changing the design of the existing code without changing its external behaviour.

In every lecture, you'll see an example of a popular code smell with Mosh's explanations about what is wrong about that code and why. You'll then learn how to change the code in a safe and step-by-step fashion while minimising breaking changes. All the source codes presented in the lectures are available for download so you can practice these techniques on your own.
