When should I use immutable objects in C#?

Immutable objects are useful when you want to ensure that the state of an object cannot change after it's created, which can help with thread safety and reduce bugs.

Can you give me an example of an immutable object in C#?

Sure! A common example is a class that represents a point in 2D space. You can define it like this:

public class Point
{
    public int X { get; }
    public int Y { get; }

    public Point(int x, int y)
    {
        X = x;
        Y = y;
    }
}

What are the benefits of using immutable objects?

Benefits include easier reasoning about code, improved performance in concurrent scenarios, and reduced chances of unintended side effects.

Are there any downsides to using immutable objects?

Yes, the main downside is that they can lead to increased memory usage and overhead since a new object must be created for any change.
