A better way to use AutoMapper to flatten nested objects?

Question

I have been flattening domain objects into DTOs as shown in the example below:

public class Root
{
    public string AParentProperty { get; set; }
    public

Not sure if this adds value to the previous solutions, but you could do it as a two-step mapping. Be careful to map in correct order if there are naming conflicts between the parent and child (last wins).

        Mapper.CreateMap();
        Mapper.CreateMap();

        var flattened = new Flattened();
        Mapper.Map(root, flattened);
        Mapper.Map(root.TheNestedClass, flattened);
