What are the best practices for using interfaces in C#?

Some best practices include keeping interfaces focused, using meaningful names, and avoiding implementation details.

Can you explain why keeping interfaces focused is important?

Keeping interfaces focused ensures that they are easier to implement and understand, promoting better code maintainability.

What do you mean by avoiding implementation details?

Avoiding implementation details means that interfaces should define 'what' a class can do, not 'how' it does it, allowing flexibility.

Are there any common mistakes to avoid when designing interfaces?

Yes, common mistakes include creating too many methods, not using inheritance wisely, and failing to consider future changes.
