12.0 Upgrade Guide¶
Equivalent settings overwrite each other¶
That applies per map and also per member. For example, you can have only one type converter per map and only one resolver per member.
It might not be obvious that some settings are equivalent. For example, a value converter is a special kind of resolver, so a ConvertUsing
will overwrite a MapFrom
for the same member.
You also cannot have for the same map/member separate configurations for Map
and ProjectTo
.
Another possible occurence is with ForAllMaps
and ForAllPropertyMaps
when it’s possible to overwrite things already set in a particular map.
ResolutionContext.Options
was removed¶
You should use ResolutionContext.Items
to access the items passed in the Map
call.
Instead of ServiceCtor
, you should use dependency injection or pass the needed objects in the Map
call.
Naming conventions¶
We’ve simplified the implementation for performance reasons. If that doesn’t work for you, you can write your own naming convention. Rather than address every peculiarity, we prefer to have a simple and fast implementation that covers most cases.
