I want to show View Model on my UI using treeview, but I could not find a way to go more than one node deep
The view should show the Persons and their Adress and their Adress details

using System.Collections.ObjectModel;
using System.ComponentModel;

public class Person : INotifyPropertyChanged
{
    public string Name { get; set; }
    public Address Address { get; set; }

    public event PropertyChangedEventHandler PropertyChanged;
}

public class Address : INotifyPropertyChanged
{
    public string Street { get; set; }
    public Postcode Postcode { get; set; }

    public event PropertyChangedEventHandler PropertyChanged;
}

public class Postcode : INotifyPropertyChanged
{
    public string Code { get; set; }
    public string Name { get; set; }

    public event PropertyChangedEventHandler PropertyChanged;
}

Tried nesting them inside each other with Datatemplates but no success
