Whether you want to use C# to build web apps, mobile apps, desktop apps or games, understanding C# classes, interfaces and principles of object-oriented programming is crucial.

This course is the second part of Mosh's best-selling C# series and is all about classes, interfaces and object-oriented programming. In essence, you'll learn:


  • How to work with classes, constructors, fields, properties, methods and indexers

  • How to use encapsulation to reduce the impact of change

  • How to improve the robustness of your code

  • How to re-use code using inheritance and composition

  • Why composition is better than inheritance

  • How to build extensible applications using polymorphism

  • How to develop loosely-coupled, extensible and testable applications using interfaces



There are lots of free tutorials and videos on YouTube. Why would you want to take this course?

The answer is simple: quality of teaching.


Mosh is a passionate software engineer with over 13 years of experience developing applications in C#. He is the author of several best-selling C# courses on Udemy and knows how to lead you through a series of baby steps in a logical way.


So, from the very beginning to the very end, you'll be confident that you'll be in good hands and watching every minute of the course, unlike the reading many free tutorials and videos, does not waste your precious time.


Each section is equipped with a balanced mix of theory and practice. At the end of each section you'll get exercises to master the concepts you learn in that section.


And one last reason: all videos are produced with high quality video/audio, to provide you the best learning experience.

"As with all of his courses his passion and love for programming is infectious. He does a great job of intermixing theory with hard examples and cautions with practicality. If you learn better by watching and examples then reading and theory this is a must watch to move beyond the learning the syntax of c#." -Michael Paul
