Wrapping an IEnumerable with an ReactiveUI Observable

Understanding that observables are not enumerables, and visa versa:

Using ReactiveUI, what are the recommended ways to wrap an IEnumerable<T> with an IObservable<T>?

For instance, given the values variable below, how could an observable be created that generates an action for each element?

var values = new int[] { 0, 1, 2, 3 };

values.ToObservable() will create an Observable based on your IEnumerable, in which you can then project each item using Select().

Also note that if you need your Observable to then return all your items into an IObservable<IEnumerable<T>>, you can buffer the list:

values.
   .ToObservable()
   .Select(x => ...)
   .Buffer(values.Count)
