C# 8 Interfaces

This course will teach you how C# interfaces can help add flexibility to your applications.

Code that is easy to maintain, extend, and test is key to applications that can move quickly to meet your users’ needs. In this course, C# Interfaces, you’ll learn to use interfaces to add flexibility to your code. First, you’ll explore the mechanics (“What are interfaces?”) and why you want to use them. Next, you’ll discover how to create your own interfaces to make it easy to change or swap out functionality. Finally, you’ll learn about default member implementation and how to avoid some common stumbling blocks. When you’re finished with this course, you’ll have the skills and knowledge of C# interfaces needed to write application code that is easy to maintain, extend, and test.
