What is new() function here?

Question

I've been learning design patterns and I saw such a method call from a class :

class Client: SubjectAccessor {
    static void Main() {
        Console.WriteLine("Proxy Pattern\n");

        ISubject subject = new Proxy();
        Console.WriteLine(subject.Requesy());

        subject = new(); //Here is what I am asking
        COnsole.WriteLine(subject.Request());
    }
}

As you can see there is a subject = new(); call there and I am wondering whether it is creating a new instance of Proxy or something else. I've not found anything related to this.

Your help is much appreciated.

If you need, I can paste the whole code or actually it is written on a book so I need to write it down here.

Thanks.

It is a typo in the book. There is no current version of C# in which that is valid (it should raise a "Type expected" compiler error). Without context it is impossible to know what it should be.
