Resolving AutoFac dependencies inside Module class

Question

I'm new to AutoFac and am currently using custom modules inside my app config to boot up some core F# systems. The code I'm using is

var builder = new ContainerBuilder();
builder.RegisterType<DefaultLogger>().As<IDefaultLogger>();
builder.RegisterModule(new ConfigurationSettingsReader("autofac"));
builder.Build();

And inside my app config I have the appropriate logic to start up the relevant systems. I would like to have access to the DefaultLogger inside my Modules. Metadata for the Module base class has the following options available to me:

protected virtual void AttachToComponentRegistration(IComponentRegistry componentRegistry, IComponentRegistration registration);

protected virtual void AttachToRegistrationSource(IComponentRegistry componentRegistry, IRegistrationSource registrationSource);

public void Configure(IComponentRegistry componentRegistry);

protected virtual void Load(ContainerBuilder builder);

I've only been using Load so far and I can't see any methods on the builder that would allow me to get at the logging service.

When registering something within your modules with autofac instead of using RegisterType method you might use Register method:

builder.Register(c =>
   {
       IComponentContext ctx = c.Resolve<IComponentContext();
       IDefaultLogger logger = ctx.Resolve<IDefaultLogger>();
       ...do something with logger...
       return ...return object you want to register...;
    });
