Exception:
An exception of type 'AutoMapper.AutoMapperMappingException' occurred in AutoMapper.dll but was not handled in user code.
Suspect the
_configurationStore.AddProfile(new OOS.PresentationModelService.AutoMapperProfile.AppProfile());
is not able to create an istance of AppProfile if i write the manual mapping it's working as expected.
_configurationStore.CreateMap<Category, Category>().ReverseMap();
