Adding Autofac to .NET core 6.0 using the new single file template

I found this Microsoft docs

var builder = WebApplication.CreateBuilder(args);

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

// Register services directly with Autofac here.
// Don't call builder.Populate(), that happens in AutofacServiceProviderFactory.
builder.Host.ConfigureContainer<ContainerBuilder>(
   builder => builder.RegisterModule(new MyApplicationModule()));

var app = builder.Build();
