What is Default Implementation?

Default Implementation is a feature introduced in C# 8.0 that allows interface methods to have an implementation. This means that interfaces can now define not only the signature of a method, but also its implementation. This is a significant change from previous versions of C#, where interfaces could only define the signature of a method, and the implementation had to be provided by the class that implemented the interface.

Why Use Default Implementation?

There are several reasons why you might want to use default implementation in your C# code. One reason is to provide a default implementation for a method that is common to all classes that implement the interface. This can save you from having to write the same code in multiple classes, and it can help to ensure that all classes that implement the interface behave in the same way.
