AffRxExtensions.Consume blocks the waiting thread on IObservable's completion

[aloslider]

I'm learning the ways how to handle observables with this library. This is an example I get a problem with:

using System.Reactive.Linq;
using LanguageExt;
using LanguageExt.Sys;
using LanguageExt.Sys.Live;
// Generates numbers from 0 to 4 each 500ms
var obs =
    Observable.Generate(
        initialState: 0,
        condition: x => x < 5,
        iterate: x => x + 1,
        resultSelector: x => x,
        timeSelector: _ => TimeSpan.FromSeconds(0.5));
await obs.Consume(x => Console<Runtime>.writeLine($"{x}").ToAff()).Run(Runtime.New());

Output: "01234" with a blocked console window, when expected a closed one.

It seems that AutoResetEvent.WaitOne() blocks the thread forever, as there's no onCompleted handler passed when subscribing to the observable.
If it's just me doing something wrong, then I would be glad to be pointed to how to work with observables (specifically, the ones created from C# events to handle them when they are fired).
