AutoMapper bidirectional mapping

Question

If I want to do bi-directional mapping, do I need to create two mapping?

Mapper.CreateMap() and Mapper.CreateMap()?

Answer 1

Yes, but if you find yourself doing this often:

public static class AutoMapperExtensions
{
    public static void Bidirectional(this IMappingExpression expression)
    {
        Mapper.CreateMap();
    }
}

then:

Mapper.CreateMap().Bidirectional();
