I'm relatively new to WPF, and I'm having trouble with what I'm fairly certain is a relatively simple problem.

I have my underlying data object, a Person:

class Person
{
    public string Surname {get; set; }
    public string Firstname {get; set; }
    public List<Address> Addresses {get; }
}

And I wish to display and edit this object in my WPF app. To this end I've created a ViewModel that I bind to in my xaml:

class PersonViewModel
{
    public string Fullname {get; }
    public ObservableCollection<AddressViewModel> Addresses {get; }
}

This is fine, except when it comes to manipulating my Address collection, where I can't work out what I should be doing:

• Should I add methods AddAddress, RemoveAddress etc... to my PersonViewModel class for manipulating my collection with instances of AddressViewModel
• Should I just add instances of AddressViewModel to my Addresses observable collection

Both of the above seem a bit messy - is there a better way of dealing with collections?
