Automapper 9.x , Mapping only if source members are not null , not working why ?

[Kasumović Mario]

Hello ,

I have upgraded old Automapper to newest , now my code don't run like expected.

       

       

        class DemoDTO

        {

            public string FirstName { get; set; }

            public string LastName { get; set; }

            public int? VacationDays { get; set; }

            public DateTime? BirthDay { get; set; }

            public Double? LoanAmount { get; set; }

        }

            var config = new MapperConfiguration(cfg => {

                cfg.AllowNullCollections = true;

                cfg.CreateMap<DemoDTO, DemoDTO>()

                .ForAllMembers(opt => opt.Condition((src, dest, srcMember, destMember) => srcMember != null));

            });

            IMapper iMapper = config.CreateMapper();

            #endregion

            var destination = new DemoDTO()

            {

                FirstName = "M",

                LastName = "M",

                LoanAmount = 2000

            };

            var source = new DemoDTO() { FirstName = "Micky", LastName = "Mouse" };

            destination = iMapper.Map<DemoDTO, DemoDTO>(source);

I am updating my entity from WebAPI , if source have any NULL values this should not be mapped with my  DESTINATION

Executing this mapping , overwrite all my fields with source , and Ignorre my Condition , bug or why happend this ?
