Message Handlers not registered in container (Autofac)

[Pabich Pawel]

Hi,

It looks like NSB can discover my handlers but it it does not register them in the container. My understanding is that NSB should discover and  register them for me: http://docs.particular.net/nservicebus/containers/.

Message: "The requested service 'TestHandler'  has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency"

Stack Trace: "at Autofac.ResolutionExtensions.ResolveService(IComponentContext context, Service service, IEnumerable`1 parameters)

   at Autofac.ResolutionExtensions.Resolve(IComponentContext context, Type serviceType, IEnumerable`1 parameters)

   at Autofac.ResolutionExtensions.Resolve(IComponentContext context, Type serviceType)

   at NServiceBus.ObjectBuilder.Autofac.AutofacObjectBuilder.Build(Type typeToBuild) in c:\BuildAgent\work\cd937cd0783294f6\src\NServiceBus.Autofac\AutofacObjectBuilder.cs:line 37

   at NServiceBus.ObjectBuilder.Common.CommonObjectBuilder.Build(Type typeToBuild)

   at NServiceBus.LoadHandlersBehavior.Invoke(IncomingContext context, Action next)

   at NServiceBus.BehaviorChain`1.InvokeNext(T context)"

Code:     configuration.UseContainer<AutofacBuilder>(c => c.ExistingLifetimeScope(container));

When I register the handler manually then everything works fine.

Any ideas how can be happening here?

Helpful information to include

  <package id="NServiceBus" version="5.2.6" targetFramework="net45" />

  <package id="NServiceBus.Autofac" version="5.0.0" targetFramework="net45" />

  <package id="NServiceBus.Serilog" version="2.0.1.1" targetFramework="net45" />

  <package id="NServiceBus.SqlServer" version="2.2.0" targetFramework="net45" />

Thanks

Pawel

Are you doing custom assembly scanning?

Can you share a repro?

[Pabich Pawel]

Nope, I will try to repro.

Are you doing anything special with TestHandler? or perhaps any container customisation?

[Pabich Pawel]

Not really.

This is the config:

    var configuration = new BusConfiguration();

            configuration.CustomConfigurationSource(new ConfigurationProvider(_queueName));

            configuration.EndpointName(_queueName);

            configuration.UseTransport<SqlServerTransport>()

                            .DisableCallbackReceiver()

                            .ConnectionString(connectionString);

            configuration.UseSerialization<JsonSerializer>();

            //http://docs.particular.net/nservicebus/persistence/

            configuration.UsePersistence<InMemoryPersistence>();

            configuration.Transactions().DisableDistributedTransactions();

            LogManager.Use<SerilogFactory>();

    configuration.UseContainer<AutofacBuilder>(c => c.ExistingLifetimeScope(container));

            Bus.Create(configuration).Start();

yep but what code creates container ?

[Pabich Pawel]

var builder = new ContainerBuilder();

            builder.RegisterModule<Module1>();

            builder.RegisterModule<Module2>();

            builder.RegisterModule<ModuleN>();

            _container = builder.Build();

and then I pass it to the code that configures the bus.

Ok then back to can you provide a way to reproduce it so i can debug into it?

[Pabich Pawel]
