如果在同一CF模型中使用了多个复杂类型类实例，则在CF模型中设置这些类的配置像这样的级别：

If multiple complex type class instances are used in same CF Model, configuration of these classes is set at CF Model level like this:

public class ContactConfiguration : EntityTypeConfiguration<Contact>
{
    public ContactConfiguration()
    {

        //props for PersonalAddress instance of Address complex type class
        this.Property(t => t.PersonalAddress.Address.Street)
            .HasColumnName("PersonalAddressStreet");

        this.Property(t => t.PersonalAddress.Address.PostalCode)
            .HasColumnName("PersonalAddressPostalCode");

        this.Property(t => t.PersonalAddress.Address.City)
            .HasColumnName("PersonalAddressCity");


        //props for BusinessAddress instance of Address complex type class
        this.Property(t => t.BusinessAddress.Address.Street)
            .HasColumnName("BusinessAddressStreet");

        this.Property(t => t.BusinessAddress.Address.PostalCode)
            .HasColumnName("BusinessAddressPostalCode");

        this.Property(t => t.BusinessAddress.Address.City)
            .HasColumnName("BusinessAddressCity");
    }
}
