For a mapping between TypeA and TypeB i would like all the boolean properties to be mapped to 'Yes' or 'No'.
I don't want to override the <bool, string>
mapping since i want that just for the mapping between TypeA and TypeB.
And I would not like to use .ForMember for each TypeA's boolean property since they are a lot.
Maybe there is a trick with ForAllMembers but I cannot make it works.
have you tried adding a mapper between Bool and String and registering it in the engine? It may be that simple, but I don't remember.
you could also create a ValueConverter and then inform the mappings to use the converter. It's been awhile since i used AM, but this sounds about right.
