AutoMapping nested models

问题:

I'm attempting to automap a model from a provider project to a wcf data contract. However they both have another model/data contract inside the original (Nested). For example: We have a client model, holds information such as name, phone number, EIN, etc... However each client can have multiple contacts (another model). How would I map this in automapper using the fluent mapping? below are the classes.

DataContracts

Client data contract

using System.Collections.Generic;
using System.Runtime.Serialization;

        public int? Id { get; set; }

        [DataMember]
        public string FirstName { get; set; }
        [DataMember]
        public string LastName { get; set; }
        [DataMember]
        public string Organization { get; set; }

        [DataMember]
        public string UserName { get; set; }

        public string Password { get; set; }

        [DataMember]
        public List<ContactDataContract> Contacts { get; set; }

        [DataMember]

        [DataMember]

        [DataMember]
        public AddressDataContract SecondaryAddress { get; set; }

Contact data contract

You have to create mappings for all classes that are used in order to map Client into ClientDataContract

Mapper.CreateMap<Client, ClientDataContract>(); 
Mapper.CreateMap<Contact, ContactDataContract>();
Mapper.CreateMap<Address, AddressDataContract>();

Wiki page says that it is enough to create Contact-to-ContactDataContract mapping and all generic collections will be mapped.
