Getting ready

Complete the Getting ready instructions at the beginning of this chapter.

How to do it…

1. Add a new folder named ComponentCollections to the MappingRecipes project.
2. Add a new class named Customer to the folder:

   public class Customer
   {
       public Customer()
       {
           Addresses=new List<Address>();
           Tags=new HashSet<string>();
       }
       public virtual Guid Id { get; protected set; }
       public virtual string Name { get; set; }
       public virtual IList<Address> Addresses { get; set; }
       public virtual ISet<string> Tags { get; set; }
   }

3. Add a new class named Address to the folder:

   public class Address
   {
       public string AddressLine1 { get; set; }
       public string AddressLine2...
