Simple Injection Registration IMappingEngine (AutoMapper)

Question

I used Autofac before, but now I want to try SimpleInjector. My problem is that when calling mapEngine in my method, I get the following error:

Missing type configuration or unsupported mapping.

Display Types: Something → SomethingDto Destination Path: IEnumerable`1 [0]

Original value:

_mappingEngine.Map<IEnumerable<SomethingDto>>(IEnumerableOfSomething); ^-- doesn't work Mapper.Map<IEnumerable<SomethingDto>>(IEnumerableOfSomething); ^-- works (That not what I want) 

Mapper.Map is not what I want. I am registering Automapper based on this here:

Replace Ninject with a simple injector

 container.Register<ITypeMapFactory, TypeMapFactory>(); container.RegisterAll<IObjectMapper>( MapperRegistry.AllMappers()); container.RegisterSingle<ConfigurationStore>(); container.Register<IConfiguration>(() => container.GetInstance<ConfigurationStore>()); container.Register<IConfigurationProvider>(() => container.GetInstance<ConfigurationStore>()); container.Register<IMappingEngine, MappingEngine>(); 

---

 Mapper.Initialize(x => { var profiles = container.GetAllInstances<Profile>(); foreach (var profile in profiles) { x.AddProfile(profile); } }); Mapper.AssertConfigurationIsValid(); 

My question ist, how can I register IMappingEngine in SimpleInjector and correctly add my profiles?

Thanks in advance!

Solved! :-)

I registered my profiles too late after running MvcControllerFactory. I hope my pseudo-example helps you prevent such an error.

 // SimpleInjector var container = new Container(); // AutoMapper registration container.Register<ITypeMapFactory, TypeMapFactory>(); container.RegisterCollection(MapperRegistry.Mappers); container.RegisterSingleton<ConfigurationStore>(); container.Register<IConfiguration>(container.GetInstance<ConfigurationStore>); container.Register<IConfigurationProvider>(container.GetInstance<ConfigurationStore>); container.RegisterSingleton(() => Mapper.Engine); // AutoMapper Profiles registration container.RegisterCollection<Profile>(new MappingAProfile(), new MappingBProfile(), new MappingCProfile()); // Adding AutoMapper profiles Mapper.Initialize(x => { var profiles = container.GetAllInstances<Profile>(); foreach (var profile in profiles) { x.AddProfile(profile); } }); Mapper.AssertConfigurationIsValid(); container.Verify(); container.RegisterAsMvcControllerFactory();
