Do I need to write all the properties explicitly when I am using AutoMapper, if these properties have the same name?

Question

I have been trying to get this going, but when i debug my test, the objects return null. I want to do complex object to object mapping but i cant get it to work.

Instead of:

cfg.CreateMap<Payments, Customer.Payments>()
    .ForMember(to => to.SomeName, opts => opts.MapFrom(from => from.SomeName))
    .ForMember(to => to.SomeDate, opts => opts.MapFrom(from => from.SomeDate));

We want to do:

    cfg.CreateMap<Payments, Customer.Payments>();

I'd definitely checkout their Wiki if you haven't already.

Based on your comment above, it looks like you're confused about the signature of mapper.map .

This is what you could do: var dest = mapper.Map<Dest>(new Source());

Checkout this simple fiddle for a working example based on the code you posted.
