Injecting dependencies into a value resolver results in a "No parameterless constructor defined for type {value resolver}"

[illuzi0n]

Source/destination types

EntityA to BaseEntityB

Mapping configuration

CreateMap<EntityA, BaseEntityB>()
        .ForMember(
          destination => destination.PropertyA,
          options =>
          {
            options.AllowNull();
            options.MapFrom<MyValueResolver>();
          })
        .ConstructUsing(job => new DerivedEntityB());

Version:

AutoMapper 10.1.1
AutoMapper.Extensions.Microsoft.DependencyInjection 8.1.1

Expected behavior

Map EntityA to DerivedEntityB

Actual behavior

No parameterless constructor defined for type {value resolver}.

The service is not resolved. I tried to use a ValueConverter before because of the base class but got the same result. Dependency injection is done with .net core default mechanism.

services.AddAutoMapper(typeof(MyMappingProfile));

Steps to reproduce

CreateMap<EntityA, BaseEntityB>()
        .ForMember(
          destination => destination.PropertyA,
          options =>
          {
            options.AllowNull();
            options.MapFrom<MyValueResolver>();
          })
        .ConstructUsing(job => new DerivedEntityB());

public class MyValueResolver : IValueResolver<EntityA, BaseEntityB, EntityC>
  {
    private readonly MyService _myService;

    public MyValueResolver (MyService myService) => _myService= myService;

    /// <inheritdoc />
    public EntityCResolve(GatewayJob source, object destination, EntityC destMember, ResolutionContext context)
      => _myService.GetEntityC(source.SomeProperty);
  }
