If I have a one-to-many relationship and I want to transorm this into a list of flat Dto-s where some attributes of parent and some of child appear in a dto, is this something that is supported out-of-box with AutoMapper? For example if I have something like this

Parent

1. ParentId
2. ParentAttr1
3. List<Child>

Child

1. ChildId
2. ChildAttr1
2. ChildAttr2

Dto

1. ParentId
2. ChildId
2. ChildAttr1
3. ChildAttr2

How do I project Parent into a Dto where for each child in parent I will get an instace of Dto?

I've setup two maps Parent->Dto and Child->Dto but just doing _mapper.Map(parentInstance) only projects parents attributes. Does this have to be done in two steps, where I would iterate children myself?
