NotImplementedException on Xamarin.iOS with linking enabled #686

I have the following code:

        Mapper.CreateMap<ShopItem, ShopItemViewModel>()
            .ForMember(s => s.ImageUrl, o => o.MapFrom(si => si.ImageGuid != null ? Urls.FileServiceUrl + "/" + si.ImageGuid : si.ImageUrl));

When I compile with "Don't link assemblies", everything works as expected, but when I select "Link SDK Assemblies only", it fails at runtime with the stack trace below. I am using mtouch arguments "--linkskip=System.Core", also tried with System.Linq and System.Linq.Expressions.

I noticed the culprit is the != check in the mapping expression; if I remove it, the error disappears.

I will workaround the error by mapping in the constructor, but this still seems like a bug that could be fixed.

Stack trace:

Linking errors are pretty hard to fix. You have to explicitly reference that method waaaaay down underneath the covers. Do that and you're set.
