use autofac in asp .net core mvc how to Use conventions to find and register components

Question

How to use autofac in .NET core to use conventions to find and register components like this

builder.RegisterAssemblyTypes(dataAccess)
       .Where(t => t.Name.EndsWith("Service"))
       .AsImplementedInterfaces();

I found builder.RegisterControllers(Assembly.GetExecutingAssembly()).Where(t=>t.Name.StartsWith("Home"));

that can't use. how can Injected xxxService into controller

Take a look at this Microsoft Doc

All you have to do is Register the service with the autofac container. For example, assuming your service types end with 'Service' you could do:

     builder.RegisterAssemblyTypes(assemblies)
       .Where(t => t.Name.EndsWith("Service"))
       .AsImplementedInterfaces()
       .InstancePerLifetimeScope();

Then use constructor injection to inject the service into the controller:

public class HomeController
{
   private IFooService fooService;
   public HomeController(IFooService fooService)
   {
        this.fooService = fooService
   }
}   

I believe RegisterControllers(...) is supposed to be used for prior versions of ASP.Net.
