Reactive Extensions (Rx) 是一个程序库，使用可观测对象(IObservable)的序列和 LINQ 风格的查询操作来编写异步和基于事件的程序。开发人员可通过 Rx 使用可观测对象来表示异步数据流，并使用 LINQ 操作来查询异步数据流。简而言之：Rx = Observables + LINQ + Schedulers.
Rx 有多个语言版本：https://github.com/ReactiveX?page=1
整个项目包含：
Reactive Extensions:
Rx.NET: The Reactive Extensions (Rx) is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators.
RxJS: The Reactive Extensions for JavaScript (RxJS) is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators in JavaScript which can target both the browser and Node.js.
Rx: The Reactive Extensions for Native (RxC) is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators in both C and C.
Interactive Extensions:
Ix: The Interactive Extensions (Ix) is a .NET library which extends LINQ to Objects to provide many of the operators available in Rx but targeted for IEnumerable.
IxJS: An implementation of LINQ to Objects and the Interactive Extensions (Ix) in JavaScript.
Ix: An implantation of LINQ for Native Developers in C
Binding Examples:
Tx: Tx is set of code samples showing how to use LINQ to events, such as real-time standing queries and queries on past history from trace and log files, which targets ETW, Windows Event Logs and SQL Server Extended Events.
LINQ2Charts: an example for Rx bindings. Similar to existing APIs like LINQ to XML, it allows developers to use LINQ to create/change/update charts in an easy way and avoid having to deal with **** XML or other underneath data structures. We would love to see more Rx bindings like this one.
