Microsoft Reactive Extensions

Microsoft Reactive Extensions (Rx) is a library that helps developers manage and process asynchronous data streams—like events, messages, or sensor data—in a more efficient and clean way. It allows you to compose and manipulate these streams using familiar programming patterns, making it easier to handle real-time updates, cancellations, or complex event sequences. Essentially, Rx provides tools to observe, filter, combine, and react to data as it flows through an application, simplifying the development of responsive programs that can handle multiple sources of information simultaneously.
