In this video, I am going to Discuss Interface Segregation Principle in C# with Examples. The Letter I in SOLID stands for Interface Segregation Principle which is also known as ISP. As part of this video, we are going to discuss the following pointers.

What is Interface Segregation Principle?
The Interface Segregation Principle states that "Clients should not be forced to implement any methods they don’t use. Rather than one fat interface, numerous little interfaces are preferred based on groups of methods with each interface serving one submodule".
Let us break down the above definition into two parts.
First, no class should be forced to implement any method(s) of an interface they don’t use.
Secondly, instead of creating large interfaces, create multiple smaller interfaces with the aim that the clients should only think about the methods that are of interest to them.
As per the Single Responsibility Principle of SOLID, like classes, interfaces also should have a single responsibility. That means we shouldn’t force any class to implement any method(s) which they don’t require.
