Clone derived class from base class method

Question

I have an abstract base class Base which has some common properties, and many derived ones which implement different logic but rarely have additional fields.

You could do something like this:

public class Base where T: Base, new()
{
    public virtual T Clone() 
    { 
        T copy = new T();
        copy.Id = this.Id;
        return copy;
    }

    public string Id { get; set; }
}

public class A : Base
{
    public override A Clone()
    {
        A copy = base.Clone();
        copy.Name = this.Name;
        return copy;
    }

    public string Name { get; set; }
}

private void Test()
{
    A a = new A();
    A aCopy = a.Clone();
}

But i doubt that it will bring something useful. I'll create another example..
