+Reactive programming provides clarity when our code needs to respond to events. The Rx.NET libraries were designed to enable cloud-native applications to process live data in reliable, predictable ways.
+
+We've written a FREE book which explains the vital abstractions that underpin Rx, and shows how to exploit the powerful and extensive functionality built into the Rx.NET libraries. 
+
+Based on Lee Campbell's 2010 book (kindly donated to the project), it has been re-written to bring it up to date with Rx.NET v6.0, .NET 8.0, and modern cloud native use cases such as IoT and real-time stream data processing.

+Introduction to Rx.NET is available [Online](https://introtorx.com/), [on GitHub](Rx.NET/Documentation/IntroToRx/), as [PDF](https://endjincdn.blob.core.windows.net/assets/ebooks/introduction-to-rx-dotnet/introduction-to-rx-dotnet-2nd-edition.pdf), and [EPUB](https://endjincdn.blob.core.windows.net/assets/ebooks/introduction-to-rx-dotnet/introduction-to-rx-dotnet-2nd-edition.epub).

 ## A Brief Introduction to Rx
 
 In this digital age, live data streams are ubiquitous. Financial applications depend on a swift response to timely information. Computer networks have always been able to provide extensive information about their health and operation. Utility companies such as water providers have vast numbers of devices monitoring their operations. User interface and game building frameworks report user interactions in great detail. Delivery vans continuously report their progress. Aircraft provide performance telemetry to detect potential maintenance issues before they become serious problems, and cars are now starting to do the same. Many of us wear or carry devices that track our physical activity and even [vital signs](https://www.youtube.com/watch?v=6yjl_h7-WYA&t=2443s). And the improvements in machine learning have enriched the insights that can be derived from the ever-increasing volume and variety of live data.

 Rx has been particularly successfully applied in user interfaces. (This is also true outside of .NET—[RxJS](https://rxjs.dev/) is a JavaScript spin-off of Rx, and it is very popular in user interface code.) The https://github.com/reactiveui/reactiveui makes deep use of Rx to support .NET UI development.

 We have set out a [roadmap](Rx.NET/Documentation/Rx-Roadmap-2023.md) explaining our medium term plans for ongoing development of Rx. This diagram illustrates our view of the platforms on which Rx is used, and the planned support lifecycles for these various targets:
 
 ![The support lifecycle for various .NET platforms, represented as a set of timelines, showing the published plans for widely used versions that are current as of 2023, with a particular focus on which versions will be current as of November 2023. The top section of the diagram shows .NET releases starting with .NET 6.0 being released in November 2021, and shows for each subsequent release occurring in November of each subsequent year, up as far as .NET 13.0 in November 2028. It also shows that even-numbered releases are Long Term Support (LTS for short) releases, supported for 3 years, while odd-numbered releases are supported only for 18 months. The section beneath this shows that .NET Framework versions 4.7.2, 4.8.0, and 4.8.1 will all be in support as of November 2023, and will continue to be in support beyond the timescale covered by this diagram, i.e., beyond November 2028. The section beneath this shows the release plan for MAUI, starting with version 8.0 on November 2023, and subsequent releases at the same time each subsequent year, up to version 13.0 in November 2028. The diagram shows that each of these versions is supported for only 18 months. Beneath this is are two lines showing Xamarin iOS 16.0, and Xamarin Android 13.0 support being active on November 2023, and running for 18 months. Beneath this is a line showing UWP version 10.0.16299 support being active on November 2023, and running beyond the timescale covered by the diagram. Beneath this is a section showing that Unity 2021 was released in 2021, and will go out of support near the end of 2023, and it shows a Unity 2022 release labelled as "Release soon," with a release date somewhere in the middle of 2023. The bottom of the diagram shows the endjin logo, and endjin's corporate motto: "we help small teams achieve big things."](Rx.NET/Documentation/RX-Platform-Support-Roadmap.png ".NET Platform Support Roadmap")
