Injecting external dependencies in Microsoft Bot Framework Dialog using Autofac

Question

I\'ve been trying to pass a service to a LuisDialog from the MessagesController like so:

public async Task Post([FromBody]Activity act

In the Global.asax.cs, you can do do the following to register your services/dialogs:

ContainerBuilder builder = new ContainerBuilder();

builder.RegisterType<IntroDialog>()
  .As<IDialog<object>>()
  .InstancePerDependency();

builder.RegisterType<JobsMapper>()
    .Keyed<IMapper<DocumentSearchResult, GenericSearchResult>>(FiberModule.Key_DoNotSerialize)
    .AsImplementedInterfaces()
    .SingleInstance();

builder.RegisterType<AzureSearchClient>()
    .Keyed<ISearchClient>(FiberModule.Key_DoNotSerialize)
    .AsImplementedInterfaces()
    .SingleInstance();

builder.Update(Conversation.Container);

In your controller, you can then resolve your main dialog as:

using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, activity))
{
    await Conversation.SendAsync(activity, () => scope.Resolve<IDialog<object>>());
}
