  hi

  However, when using the same mappings inside a service that derives from the ABP identity service:

  hi

  Thanks. Can you also share some code of the mapper and your custom app service?

  Hi,

  please use below code in a new project.

  using System;
  
  using System.Linq;
  
  using System.Threading.Tasks;
   
  using Microsoft.AspNetCore.Identity;
  
  using Microsoft.Extensions.Options;
   
  using Volo.Abp.Application.Dtos;
  
  using Volo.Abp.Authorization.Permissions;
  
  using Volo.Abp.Caching;
  
  using Volo.Abp.EventBus.Distributed;
  
  using Volo.Abp.Identity;
  
  using Volo.Abp.Threading;
   
  namespace Test.Identity;
   
  public class MyIdentityUserAppService : IdentityUserAppService
  
  {
  
      public MyIdentityUserAppService(
  
              IdentityUserManager userManager,
  
              IIdentityUserRepository userRepository,
  
              IIdentityRoleRepository roleRepository,
  
              IOrganizationUnitRepository organizationUnitRepository,
  
              IIdentityClaimTypeRepository claimTypeRepository,
  
              IdentityProTwoFactorManager twoFactorManager,
  
              IOptions<IdentityOptions> identityOptions,

              ICancellationTokenProvider cancellationTokenProvider)
  
              : base(
  
                  userManager,
  
                  userRepository,
  
                  roleRepository,
  
                  organizationUnitRepository,
  
                  claimTypeRepository,
  
                  twoFactorManager,
  
                  identityOptions,
  
                  eventBus,
  
                  abpIdentityOptions,
  
                  permissionChecker,
  
                  userDownloadTokenCache,
  
                  importInvalidUsersCache,
  
                  sessionManager,
  
                  userTwoFactorChecker,
  
                  cancellationTokenProvider)
  
      {
  
      }
   
      public async Task<PagedResultDto<LookupDto<Guid>>> GetDummy(LookupRequestDto input)
  
      {
  
          var users = await UserRepository.GetListAsync();
   
          var items = users.Select(ObjectMapper.Map<IdentityUser, LookupDto<Guid>>)
  
                  .OrderBy(u => u.DisplayName)
  
                  .ToList();
   
          return new PagedResultDto<LookupDto<Guid>>(items.Count, items);
  
      }
  
  }
   
  

  See below AutoMapper configuration below:

  CreateMap<IdentityUser, LookupDto<Guid>>()
              .ForMember(
                  d => d.DisplayName,
                  m => m.MapFrom(s =>
                      s.Name + " " +
                      s.Surname + " (" +
                      s.UserName + ")"));
   
  

  Thanks, S.

  hi

  The issue is caused by a breaking change in ABP v10. IdentityUserAppService sets ObjectMapperContext = typeof(AbpIdentityApplicationModule), which forces the inherited ObjectMapper to use Mapperly (the new default in v10). Your AutoMapper profile is not visible in that context.

  Here are two ways to fix it:

  ---

  Option 1: Keep Using AutoMapper

  Inject AutoMapper's IMapper directly into your service and use it instead of the inherited ObjectMapper:

  public class MyIdentityUserAppService : IdentityUserAppService
  {
      private readonly IMapper _mapper;
  
      public MyIdentityUserAppService(
          IdentityUserManager userManager,
          IIdentityUserRepository userRepository,
          IIdentityRoleRepository roleRepository,
          IOptions<IdentityOptions> identityOptions,
          IPermissionChecker permissionChecker,
          IMapper mapper
      ) : base(userManager, userRepository, roleRepository, identityOptions, permissionChecker)
      {
          _mapper = mapper;
      }
  
      public LookupDto<Guid> GetDummy(IdentityUser user)
      {
          return _mapper.Map<LookupDto<Guid>>(user);
      }
  }
  

  Your existing AutoMapper profile (CreateMap<IdentityUser, LookupDto<Guid>>) works as-is. No other changes needed.

  ---

  Option 2: Migrate to Mapperly (Recommended)

  Create a Mapperly mapper class. ABP will automatically discover and register it:

  public class IdentityUserToLookupDtoMapper : MapperBase<IdentityUser, LookupDto<Guid>>
  {
      public override LookupDto<Guid> Map(IdentityUser source)
      {
          return new LookupDto<Guid>
          {
              Id = source.Id,
              DisplayName = $"{source.Name} {source.Surname} ({source.UserName})"
          };
      }
  }
  

  Then remove the CreateMap<IdentityUser, LookupDto<Guid>>() entry from your AutoMapper profile.

  For more details, see: https://abp.io/docs/latest/framework/infrastructure/object-to-object-mapping#mapperly-integration
