Properties referencing their class

Given the following class example:

 csharp
class Node
{
    public Node LeftNode { get; set; }
    public Node RightNode { get; set; }
    public int Data { get; set; }
}

 csharp
class Node
{
    public Node LeftNode { get; set; }
    public Node RightNode { get; set; }
    public int Data { get; set; }
}

How do the Node properties work here? Do they create new instances of the class?

yes ofc

var root = new Node(0);
root.Left = new Node(1);
root.Right = new Noe(2);
root.Left.Left = new Node(3);

var root = new Node(0);
root.Left = new Node(1);
root.Right = new Noe(2);
root.Left.Left = new Node(3);

theyre initialized to whatever 0 means for the type which is null for reference types and 0 for ints

(also the equivalent of 0 for any struct, including numbers)
