Setting up Rx.NET
To configure our .NET-based application to use the Rx.NET classes, we can simply ask NuGet to download the Rx-Main (Reactive Extensions - Main Library) package.
This action will register all .NET assemblies in our application, including other NuGet packages, such as Rx-Core, Rx-Interfaces, Rx-PlatformServices, and Rx-Linq, all from Microsoft Corp.
NuGet Rx-Main package
Other packages are available using NuGet. This book will cover only the mainline of such package distributions.
At the time of writing this book, Rx was available in version 2.2.5 that was released in July 2014. Although in May 2015 a version 2.3.0 beta was available throughout NuGet, a stable 2.3.x release is still not available.
A stable version 2.x was available in August 2012, supporting .NET 4.0, 4.5, 4.5 for Store Apps, Windows Phone 7.5, and Silverlight 5.
