System.Reactive.Interfaces
The System.Reactive namespace contains interfaces and classes used throughout the Reactive Extensions library.
The System.Reactive.Concurrency namespace contains interfaces and classes that provide the scheduler infrastructure used by Reactive Extensions to construct and
process event streams. Schedulers are used to parameterize the concurrency introduced by query operators, provide means to virtualize time, to process historical data,
and to write unit tests for functionality built using Reactive Extensions constructs.
The System.Reactive.Disposables namespace contains interfaces and classes that provide a compositional set of constructs used to deal with resource and subscription
management in Reactive Extensions. Those types are used extensively within the implementation of Reactive Extensions and are useful when writing custom query operators or
schedulers.
The System.Reactive.Linq namespace contains interfaces and classes that support expressing queries over observable sequences, using Language Integrated Query (LINQ).
Query operators are made available as extension methods for IObservable<T> and IQbservable<T> defined on the Observable and Qbservable classes, respectively.
The System.Reactive.Subjects namespace contains interfaces and classes to represent subjects, which are objects implementing both IObservable<T> and IObserver<T>.
Subjects are often used as sources of events, allowing one party to raise events and allowing another party to write queries over the event stream. Because of their ability to
have multiple registered observers, subjects are also used as a facility to provide multicast behavior for event streams in queries.
