I'm using Mapster with DI and I'm trying to map objects that I receive from WS. I was following this guide https://github.com/MapsterMapper/Mapster/wiki/Dependency-Injection#mapping

I register TypeAdapterConfig, and ServiceMapper

var config = new TypeAdapterConfig();
services.AddSingleton(config);
services.AddScoped<IMapper, ServiceMapper>();

Blacklist class contains collection of Cards but webservice returns array of long, that I remap to object.

public class BlacklistMapper : IRegister
{
    void IRegister.Register(TypeAdapterConfig config)
    {
        config.NewConfig<long, Internal.BlacklistCard>()
            .Map(dest => dest.Cuid, source => source);

        config.NewConfig<SzWebService.BlackList, Internal.Blacklist>()
            .Map(dest => dest.Id, source => source.iBlacklistId)
            .Map(dest => dest.Crc, source => source.iBlackListCRC)
            .Map(dest => dest.Cards, source => source.lCuid);
    }
}

Inject mapper in the constuctor

 private readonly IMapper _mapper;

 public Service(IMapper mapper)
 {
     _logger = logger;
 }

And finally call it like so

_mapper.Map<Blacklist>(response.mBlackListData)

The result is always object with default values

Step 1 - Create the configuration via implementing IRegister

public class BlacklistMapper : IRegister
{
    void Register(TypeAdapterConfig config)
    {
        config.NewConfig<SzWebService.BlackList, Internal.Blacklist>()
            .Map(...)
            .Map(...);
    }
}

Step 2 - Register the configuration

You can either register the configuration explicitly:

var config = new TypeAdapterConfig();

// Explicitly apply a specific configuration
config.Apply(new BlackListMapper());

services.AddSingleton(config);
services.AddScoped<IMapper, ServiceMapper>();

or let Mapster scan your assemblies for IRegister implementations:

// Scan & apply IRegisters automatically.
config.Scan(Assembly.GetExecutingAssembly());
