Abstract: Best practices tell us to program to an interface rather than a concrete class. Let’s start by understanding what a .NET Interface is and what it means to our code. After that, we’ll look at a couple of practical implementations that can make our code more robust and extensible. No specific experience with interfaces or abstract classes is required, but knowing the basics of .NET programming will be helpful.
