AutoMapper cannot convert enum to nullable int?

Question

I got AutoMapperMappingException exception

Exception of type \'AutoMapper.AutoMapperMappingException\' was thrown. ---> System.InvalidCastException: I

Answer 1

Just in case if anyone want to try using a type converter

Mapper.CreateMap().ConvertUsing(new FooTypeConverter());

public class FooTypeConverter: TypeConverter
    {
        protected override DummyTypes.Foo? ConvertCore(int? source)
        {
            return source.HasValue ? (DummyTypes.Foo?)source.Value : null;
        }
    }

Cheers
