Explain SOLID principles

Please Explain SOLID principles and provide examples in C#.

SOLID is an acronym representing five design principles intended to make software designs more maintainable, flexible, and scalable.

• Single Responsibility: A class should have only one reason to change.
• Open/Closed: Software entities should be open for extension but closed for modification.
• Liskov Substitution: Subclasses must be replaceable by their base classes without breaking functionality.
• Interface Segregation: Clients should not be forced to depend on methods they do not use.
• Dependency Inversion: Depend on abstractions, not on concretions.

public interface ILogger { void Log(string message); }
public class ConsoleLogger : ILogger { public void Log(string message) => Console.WriteLine(message); }
public class UserService {
    private readonly ILogger _logger; 
    public UserService(ILogger logger) => _logger = logger;
    public void CreateUser(string name) => _logger.Log($"User {name} created");
}
