From Zero to Hero: Writing Clean Code with C#
Learn how to write clean, maintainable C# code using modern Clean Code practices. This course covers essential principles like readability and simplicity for more efficient development.
About This Course
"Clean Code" is one of the most used phrases in software engineering but
is also one of the most misused. What does Clean Code mean, and what makes
our code dirty or clean? The concept was popularized by Robert C. Martin or
"Uncle Bob", and it is a set of practices that will help you write code that
is easier to change, read and understand and less prone to mistakes or issues
when it comes time to change or expand it. In this course, Gui Ferreira will teach
you everything you need to know to start writing excellent C# code using the
knowledge he gained after years of writing clean code professionally for big companies.
