Infrastructure Services/Domain and Encapsulation

[mweel1]

I'm trying to put all my logic in the domain models so I don't have a anemic domain models.

Here is an example

CommandHandler () {

paymentReferenceId = _infastructure_payment.process($12);

var appt = new Appt(startDate,endDate, paymentReferenceId);

Where does this go? If I leave it in the command handler, then I am not really encapsulating my logic to create a new appointment.

1. Do I pass the reference id in as a value to the constructor of Appt (as shown)?
2. Do I pass the _payment service into the domain and have it run the transaction?
3. Do I create a service and truly encapsulate the domain and infrastructure logic in there?
