Have you dealt with implementing or applying interface constructs in your projects?

In C#, interfaces are used to define contracts that classes or structures must implement. This allows for creating flexible and extensible architectures.

Example of an interface and its implementation:

public interface ILogger
{
    void Log(string message);
}

public class ConsoleLogger : ILogger
{
    public void Log(string message)
    {
        Console.WriteLine(message);
    }
}

This approach allows changing the logger implementation without modifying the code that uses it, which improves testability and maintainability.
