How to implement ioc for Automapper (IMappingEngine) using Unity in webapi project

Question

I am developing webapi project and extensively using Automapper to map objects. Currently i am using Mapper.Map

Can anyone direct me how to implement this? How to call this configure method while registering IMappingEngine in Unity?

My current automapper mapping:

public static class AutomapperConfiguration { public static void Configure() { Mapper.Initialize(cfg => { cfg.ConstructServicesUsing(type => UnityConfig.GetConfiguredContainer().Resolve(type)); cfg.CreateMap<Logger, Log>() .ForMember(d => d.TxId, opt => opt.ResolveUsing<AsRunTxIdValueResolver>()); } } }

Thanks

You can use automapper profiles to create various mappers and register all profiles like this:

public static class AutomapperConfiguration { public static MapperConfiguration MyMapperConfiguration; public static void Configure() { MyMapperConfiguration = new MapperConfiguration(cfg => { var types = typeof(Program).Assembly.GetTypes(); var profiles = types.Where(x => x.IsSubclassOf(typeof(Profile))) .Select(Activator.CreateInstance) .OfType<Profile>() .ToList(); profiles.Each(p => cfg.AddProfile(p)); }); MapperConfiguration.AssertConfigurationIsValid(); } }

Your automapper profile class will look like this:

public class LoggerProfile : Profile { protected override void Configure() { CreateMap<Logger,Log>() .ForMember(d => d.TxId, opt => opt.ResolveUsing<AsRunTxIdValueResolver>()); } }

In your startup.cs, you would have to register the mappers like this:

AutoMapperConfiguration.RegisterMappers();

How do use it as with dependency injection? There used to be an IMappingEngine once
