This course will help leverage your conceptual understanding to produce proper object-oriented code, where objects will completely replace procedural code for the sake of flexibility and maintainability.

Programmers do have conceptual understanding of OO concepts, but often fail to turn that into a proper object-oriented code. In this course, Making Your C# Code More Object-oriented, you’ll learn how to create proper object-oriented code. First, you’ll learn how to avoid branching and looping. Next, you’ll learn how to avoid Boolean expressions. Finally, you’ll learn how to make domain logic implementation dynamic and configurable. By the end of this course, you’ll be able to recognize your own error of the past and build more correct coding style.
