Register different assembly types in autofac container in As

Question

I have 3 tire architecture application. In my Data Access is like below:

ICategoryRepository.cs

public interface ICategoryRepository {         void Add(Category category); } 

CategoryRepository.cs

 internal class CategoryRepository :ICategoryRepository   {      void ICategoryRepository.Add(Category category)       {               // Dbcontext goes here       }    } 

And I have a Autofac model to register the above classes in autofac container is:

public class RepositoryModule : Module     {         protected override void Load(ContainerBuilder builder)         {             var assembly = System.Reflection.Assembly.GetExecutingAssembly();             builder.RegisterAssemblyTypes(assembly).Where(t => t.Name.EndsWith("Repository")).AsImplementedInterfaces();             base.Load(builder);         }     } 

And I have a service layer as below: ICategoryService.cs

public interface ICategoryService {   void Add(Category category); } 

CategoryService.cs

internal class CategoryService : ICategoryService {   private ICategoryRepository _categoryRepository;   public CategoryService(ICategoryRepository cateoryRepository)   {      _categoryRespoitory = categoryRepository;    }   void ICategoryService.Add(Category category)   {    _categoryRepository.Add(category);   } } 

Similarly, I have a module to register the above class in container as,

public class ServiceModule : Autofac.Module     {         protected override void Load(ContainerBuilder builder)         {             var assembly = System.Reflection.Assembly.GetExecutingAssembly();              builder.RegisterAssemblyTypes(assembly).Where(t => t.Name.EndsWith("Service")).AsImplementedInterfaces().InstancePerLifetimeScope();                                 }     } 

And in my Web, Global.asax.cs:

 public class Global : System.Web.HttpApplication, IContainerProviderAccessor     {         static IContainerProvider _containerProvider;          public IContainerProvider ContainerProvider         {             get { return _containerProvider; }         }          void Application_Start(object sender, EventArgs e)         {              var builder = new ContainerBuilder();               var assembly = System.Reflection.Assembly.GetExecutingAssembly();              _containerProvider = new ContainerProvider(builder.Build());          }     } 

Here my question is, how can call the service and DataAccess module from the web.[I don't have the data access reference in my web, but I have reference of service module in my web]

Thanks in advance.
