How can I make AutoMapper ignore our BaseClass ViewModel properties?

I added the following

public class AutoMapperConfig
    {
        public static MapperConfiguration mapperConfiguration = new MapperConfiguration(cfg =>
        {
            cfg.AddProfile(new MappingProfile());
            cfg.ShouldMapProperty = pi => !pi.Name.InList( "HiddenSwitch","ErrorMessage","SuccessMessage", "WarningMessage","DuplicateForm"); // this is the line I added
        });
        public static IMapper Mapper;

        public static void Configure()
        {
            Mapper = mapperConfiguration.CreateMapper();
            mapperConfiguration.AssertConfigurationIsValid(); // This line I added
        }
    }

But I still got these properties listed as unmapped.
