Disable disposable resource tracking for a service in Autofac

NoResourceTrackingInAutofac.cs

var builder = new ContainerBuilder();

// The thing we want to create haphazardly without ever
// disposing it or any of its dependencies:

builder.RegisterType<Foo>()
    .Named<IFoo>("untracked");

// Owned<T> is itself untracked (i.e. disposal is up to the
// owner.) Since we just let the Owned<IFoo> slip away, it
// will be GC'ed. Owned<T> doesn't implement a finalizer (and
// nor should it) so any IFoos resolved this way will stick around happily
// until they're GC'ed themselves.

builder.Register(c => c.ResolveNamed<Owned<IFoo>>("untracked").Value)
    .As<IFoo>();

var container = builder.Build();

var factory = container.Resolve<Func<IFoo>>();

while (true)
    var untrackedFoo = factory();
