What you'll learn

It's easy to write software that fulfills its users' immediate needs, but is difficult to extend and maintain. Such software becomes a burden for companies striving to remain competitive. In this course, SOLID Principles for C# Developers, you will learn five fundamental principles of object-oriented design that will keep your software loosely coupled, testable, and maintainable. First, you will see how to keep classes small and focused, and how to extend their behavior without having to edit their source code. Then, you will discover the importance of properly designing interfaces and abstractions in your systems. Finally, you will explore how to arrange dependencies in your system so different implementations can be added or plugged in as needed, allowing a truly modular design. When you are finished with this course, you will understand how to build maintainable, extensible, and testable applications using C# and .NET.
