  1. The static version of the CreateMap method was deprecated in 4.2, then removed from the API in version 5.0. Jimmy Bogard talks about this in more detail in this blog post.

    The new technique for mapping is non-static, like this (code is from the post):

    var config = new MapperConfiguration(cfg => {
        cfg.CreateMap<Source, Dest>();
    });
    
    IMapper mapper = config.CreateMapper();
    var source = new Source();
    var dest = mapper.Map<Source, Dest>(source);

  3. Here is how I used AutoMapper in my code.

    Step 1 : Downloaded AutoMapper through nuget-packages.

    Version is

    <package id="AutoMapper" version="6.1.1" targetFramework="net452" />
    

    Step 1 : Created DTO class

    public class NotificationDTO
    {
    
        public DateTime DateTime { get; private set; }
        public NotificationType Type { get; private set; }
        public DateTime? OriginalDateTime { get; private set; }
        public string OriginalVenue { get; private set; }
        public ConcertDTO Concert { get; set; }
    }
    
    public class ConcertDTO
    {
        public int Id { get; set; }
        public bool IsCancelled { get; private set; }
        public DateTime DateTime { get; set; }
        public string Venue { get; set; }
    
    }
    

    Step 2 : Created an AutoMapperProfile class which inherits from Profile

    using AutoMapper;
    using ConcertHub.DTOs;
    
    namespace ConcertHub.Models
    {
      public class AutoMapperProfile : Profile
      {
        public AutoMapperProfile()
        {
            CreateMap<Concert, ConcertDTO>();
            CreateMap<Notification, NotificationDTO>();
        }
      }
    }
    

    Step 3 : Registered AutoMapperProfile in the Application Start method of Global.asax file

    protected void Application_Start()
        {
            AutoMapper.Mapper.Initialize(cfg => cfg.AddProfile<AutoMapperProfile>());
    
        }
    

    Finally the magic piece of code in the Api Controller

    public IEnumerable<NotificationDTO> GetNewNotification()
        {
            var userId = User.Identity.GetUserId();
            var notifications = _dbContext.UserNotifications
                    .Where(un => un.UserId == userId && !un.IsRead)
                    .Select(un => un.Notification)
                    .Include(n => n.Concert)
                    .ProjectTo<NotificationDTO>()//use Automapper.QueryableExtension namespace
                    .ToList();
    
            return notifications;
        }
    

    Hope it helps .

  5. Here is how it works now:

            Mapper.Initialize(cfg =>
            {
                cfg.CreateMap<SupervisorEmployee, SupervisorViewModel>()
                .ForMember
                    (dst => dst.Name, src => src.MapFrom<string>(e => SupervisorViewModel.MapName(e)))
                .ForMember
                    (dst => dst.OfficePhone, src => src.MapFrom<string>(e => e.OfficePhone.FormatPhone(e.OfficePhoneIsForeign)))
                .ForMember
                    (dst => dst.HomePhone, src => src.MapFrom<string>(e => e.HomePhone.FormatPhone(e.HomePhoneIsForeign)))
                .ForMember
                    (dst => dst.MobilePhone, src => src.MapFrom<string>(e => e.MobilePhone.FormatPhone(e.MobilePhoneIsForeign)));
            });
