DEFAULT INTERFACE

The default interface implementation (default interface implementation) in C# is a feature introduced starting with C# 8.0. This feature allows you to provide default implementations for methods within interfaces, thus reducing the need to modify all classes that implement an interface when a new method is added. The following is a detailed description of how to use this feature.

1. Defining an interface with a default implementation

In C#, an interface can now contain methods with method bodies, providing a default implementation that can be used by the classes that implement the interface. Here is an example of an interface with a method body with a default implementation:

public interface IExample

2. Implementation of an interface in a class

When a class implements an interface with predefined methods, you do not need to provide an implementation for those methods unless you want to override them. Here is an example:

public class ExampleClass : IExample

3. Using the methods of the interface

When using a class that implements the interface, methods with default implementations can be called like any other method:

class Program

4. Overriding a default method

If you want to provide your own implementation of a default method, you can do so in the class:

public class CustomExampleClass : IExample
