builder.Host.UseServiceProviderFactory(new AutofacServiceProviderFactory());

// Add services to the container.
builder.Services.AddControllersWithViews();

//Register your own things directly with Autofac here
builder.Host.ConfigureContainer<ContainerBuilder>(builder => builder.RegisterType<Service>().As<IService>());

var app = builder.Build();
