Enhance Process.ReadAllLinesAsync

[NeverMorewd]

Consider adding a new ReadAllLinesAsync overload that returns IObservable<ProcessOutputLine>.

You can open an API proposal to discuss further. Note that the new method has to have a different name.

Generally I don't expect it to be approved. The BCL doesn't provide any concrete implementation of IObservable, and Rx provides easy conversion from IEnumerable to IObservable.

[NeverMorewd]

Yes, I think it is more appropriate to implement it in Rx.
