Programmer - AutoMapper with c# 2.0 syntax

Programmer Question

I'm trying to create a custom mapping with AutoMapper, but I can't use 3.0 syntax with lambdas. How would one convert this 3.0 code into 2.0 ?

Mapper.CreateMap<MyClass, MyDto>()
 .ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.CompanyName))
