Automapper maping navigation property on a one to one relationship

I'm trying to map a navigation property on a one to one relationship but I'm getting null values, here are my entities

   public class Client
   {
        public int ClientId { get; set; }
        public string Name { get; set; }
        public int BranchId { get; set; }
        public Branch Branch{ get; set; }
   }

   public class Branch
   {
        public int BranchId { get; set; }
        public string Name { get; set; }
   }

And this is my Dto

   public class ClientDto
   {
        public int ClientId { get; set; }
        public string Name { get; set; }
        public string BranchName { get; set; }
   }

And these are the mapping configurations I have tried

   public class MappingProfile : Profile
    {
        public MappingProfile()
        {
            CreateMap<Client, ClientDto>().
                ForMember(
                dest => dest.BranchName, 
                opt => opt.MapFrom (src => src.Branch.Name)
                );
        }
    }

and

           CreateMap<Client, ClientDto>().IncludeMembers(src => src.Branch);
           CreateMap<Branch, ClientDto>().ForMember(
              dest => dest.BranchName, 
              opt => opt.MapFrom(b => b.Name)
            );

in both cases I got nulls on BranchName, thank you.

You need to Include the navigation property on your repository (if using) implementation:

var client = await _context.Clients.Include(c => c.Branch).FirstOrDefaultAsync(c => c.Id == id);

Please make sure your actual object (usually from database using ef) includes the desired navigation property by using the Include – S. M. JAHANGIR

This is the correct answer.
