```csharp

var customer = new Customer();

customer.Lastname = "Doe";

customer.Firstname = "Jack";

customer = customer.AsTrackable();

customer.Firstname = "John";

var trackableCustomer = (ITrackableObject)customer;

bool isChanged = trackableCustomer.IsChanged; // -> true

foreach(IPropertyChange changedProperty in trackableCustomer.ChangedProperties)

{

    if(changedProperty is SimplePropertyChange simpleProperty)

    {

        Console.WriteLine(simpleProperty.Name); // -> "Firstname"

        Console.WriteLine(simpleProperty.OldValue); // -> "Jack"

        Console.WriteLine(simpleProperty.CurrentValue); // -> "John"        

    }

    else if(changedProperty is CollectionPropertyChange collectionProperty)

    {

        Console.WriteLine(collectionProperty.Name);

        

        foreach(var added in collectionProperty.Added)

        {

             Console.WriteLine("Added: " + added);

        }

        

        foreach(var removed in collectionProperty.Removed)

        {
