If you are coming to this series of posts for the first time you might check out my introductory post for a little context.
Stimpack is another project leveraging ReactiveExtensions (RX). It?s based off of ReactiveUI and has some interesting concepts for consideration with a MVVM pattern.
This was probably originally added to my To-Research list mostly because of the RX factor.
I didn?t find an good sample project on how to use it, but if you read through the fairly clean test project you can probably figure out anything you need.
