These days, anyone can code. But if you want to get a job as an intermediate or senior-level C# developer, you must know how to write clean, maintainable code.

As Martin Fowler said:

"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 does separate poorly written code (aka code that smells) from beautiful code that talks?

In this course, Mosh, author of several best selling C# courses on Udemy, walks you through common code smells found in C# programs and shows you 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 commentary about what is wrong with that code and more importantly, 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.

By the end of this course, you'll be able to

  • Spot the smells in your code
  • Refactor your code using safe and fast refactoring techniques with ReSharper
  • Write clean code that is more readable and maintainable
  • Break long methods into smaller, more maintainable ones
  • Simplify nested / complex conditional blocks
  • Design the proper signature for your methods
  • Remove duplicated code
  • Refactor long switch/case blocks into an object-oriented design using polymorphism
  • And more...

Understanding and using these techniques are absolutely essential skills that every C# developer must have.

It includes the most valuable tips I have received for 5 years. Thank you Mosh you helped me a lot." -Se He

"Just Love It. Its the 4th course i bought from Mosh, and i do not regret spending any money. I'm working as a developer for 2-3 years now but keep loosing myself in code written by me / others. I can finally understand why and what to change. Thanks Mosh. " -Klaus Prünster

"This course was really great at explaining clean coding practices in a way which is easy to follow and understand. Highly recommended. " -Edin Livnjak

"Another fantastic course from Mosh. I have't seen another course that explains these essential concepts so clearly. In my opinion all Developers should be taught this type of thing before being let loose within a work environment." -Mark Baker

"This course is awesome. It's highly detailed (but easy to understand nonetheless). It has, for me personally, the right amount of information density; Mosh picked exactly the right speed of teaching and progressively intensifies the content, which is great. It is definitively worth the time and money, and one can clearly see the passionate effort the author has put in the creation of these materials. Big respects. " -Raphael Beck
