RX – Everything is a stream!

Introduction

I’m a huge fan of Reactive Extensions (RX) and have been using it in a professional context for many years.  One of the interesting topics of debate between co-workers is when to use Tasks and when to use RX.  This post is about my opinion, which might be well off, but at least I have shared it and hopefully receive some compelling counter arguments.

RX – What thread am I on?

Introduction

Threading in RX is usually performed by a set of classes called Schedulers, that implement the IScheduler interface.  I have interviewed a fair few people who don’t fully understand what thread they are on at various points in the pipeline, especially when we throw in a few ObserveOn and SubscribeOn calls.
