AutoMapper bidirectional mapping

Question

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

Mapper.CreateMap<A, B>() and Mapper.CreateMap<B, A>()?

Answer 1

Yes, but if you find yourself doing this often:

public static class AutoMapperExtensions {     public static void Bidirectional<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)     {         Mapper.CreateMap<TDestination, TSource>();     } } 

then:

Mapper.CreateMap<A, B>().Bidirectional();
