This document provides an overview of Reactive Extensions (Rx), a library for composing asynchronous and event-based programs using observable collections. It discusses the core interfaces like IObservable and IObserver, and how Rx allows composing programs using operators like Merge and Zip. Rx can be used to work with events, asynchronous code, and interactive UI code. The document also lists several Rx-related libraries and frameworks, and provides resources for learning more about Rx.

Editor's Notes
- давайте вспомним buzzwords: Azure, Silverlight, Windows Phone
- Speaker tips:The essential difference is who controls how the data is received.Philosophically this is nothing but how the application and the environment work together.Looking from the application’s point of view:Does it ask the environment – interactively – for data? enumerableDoes it passively wait for the environment to send data and react to it? observableBoth are complementary models. One doesn’t (aim to) replace the other.Matter of which one aligns more closely to which model:SQL’ s TDS protocol is pull-based, hence IE<T> is the best fit.Stock broker services may be push-based, hence IO<T> is a better match.Will see how one can convert between those.
