A brief guide to extensions, namespaces and assemblies in V1 of Reactive Extensions (Rx)

Exploring the latest release of Reactive Extensions, I discover that the different types and extension methods have been split across namespaces and assemblies.

I know that I can go looking one by one on MSDN, but what I'd like is a brief overview of the logic of this segregation (I don't mean a justification, but if you're looking for this开发者_开发知识库, try here first).

Assemblies

• System.Reactive.dll - The core APIs
• System.Reactive.Providers.dll - IQbservable interfaces and implementation over objects
• System.Reactive.Windows.Forms.dll - Schedulers and integration for WinForms
• System.Reactive.Windows.Threading.dll - Schedulers and integration for WPF/Silverlight
• Microsoft.Reactive.Testing.dll - Classes for testing Rx- Mocks, Recorders, Virtual schedulers, etc

Namespaces

• System.Reactive.Concurrency - Schedulers
• System.Reactive.Disposables - Classes for creating and using disposables. (I was sad to see these classes moved into the Rx specific namespace, as they are generally useful)
• System.Reactive.Joins - Join matching patterns
• System.Reactive.Linq - Combinators and extension methods on IObservable and IQbservable. This is the main namespace for most consumers
• System.Reactive.Subjects - Subject implement both IObservable and IObserver and have state
• System.Reactive.Threading.Tasks - Interop to the TPL
