AutoMapper: Mapping nested complex types

Some production code I was working on wasn't working as expected, so I thought I'd spike it out. AutoMapper allows you to map between, say, a service layer and a DTO without you having to write hardly any code. Install it with NuGet. Here is an example. I have some types in my service layer: namespace Automapper.Spike.Example1.Contract { public class CreateOrderRequest { public int Id { get; set; } public int NumberOfItems { get; set; } public Customer Customer { get; set; } } public class Customer { public int Id { get; set; } public string FullName { get; set; } public string Postcode { get; set; } } } I want to map these to a DTO layer for storage: namespace Automapper.Spike.Example1.Dto { public class Order { public int Id { get; set; } public int NumberOfItems { get; set; } public Customer Customer { get; set; } } public class Customer { public int Id { get; set; } public string Name { get; set; } public string Postcode { get; set; } } } I just need to tell AutoMapper that I want it to map between these types: public class MapperConfiguration { public void Configure() { Mapper.
