Rx.NET is a reactive programming framework and library for the .NET ecosystem used to compose asynchronous and event-based programs. It provides an observable data stream API that treats live sequences of information as collections, allowing developers to coordinate asynchronous event workflows using a declarative syntax.
The project functions as an extension of language integrated query patterns to asynchronous streams. This allows for the filtering and transformation of asynchronous notifications and event sequences through the application of query operators.
The framework covers asynchronous event processing and real-time data streaming. It enables the coordination of event-driven workflows and the integration of non-blocking APIs to manage data flows and state changes.
