I don't understand how to delete some of the related entities in a single save of the entity.

I have CompanyEntity and a 1:m child entity CompanyAddress

If I want to delete one or more company addresses, do I need to call a DeleteEntity on each one or can I somehow just save the company, and if so, how do I mark the companyaddresses that I want to delete?

Thanks

Deletes aren't done when you save, when you save, changes are saved, no deletes are performed. If you want to delete entities, either add them to a collection and delete the collection, or preferably use a UnitOfWork object to perform the saves and the deletes in one go.
