Summary: In this video, we are covering "Using" and "Finally". In the case of "Using", it takes two parameters: the first one is a Func that returns a StreamReader, and the second is a Func that takes the StreamReader from the first parameter and returns an IObservable of string. Then, we will do our standard ToObservable() on a new thread. And call Finally which comes handy whether the sequence terminates normally or by an exception.
When we subscribe, we implement our OnNext(), OnError(), and OnComplete()methods.
Methodology of the development of example: Good coding standard and simplified design to illustrate the key points.
