If you’re not familiar with the Rxx project yet, it's something I’ve been working on for several months now along with James Miles.
Rxx is a library of unofficial reactive LINQ extensions supplementary to Microsoft's Reactive Extensions for .NET (Rx). Rxx is developed entirely in C# and targets the .NET Framework 4.0, Silverlight 4.0 and Windows Phone 7 (WP7).
Why should you use Rx and Rxx?
Well, if you’re doing any kind of programming that involves asynchrony or concurrency, such as what is commonly found in UI layers, business layers, data access layers, middle tier services – basically everywhere, then you’ll definitely find Rx to be very useful. Rxx adds a whole bunch of useful features on top of Rx and the .NET Framework Class Library (FCL), making it quite easy to introduce common patterns of asynchrony into any .NET program through the use of IObservable<T> and LINQ.
Rxx provides the following features. See the Documentation for details.
- Many IObservable<T> extension methods and IEnumerable<T> extension methods.
- Many useful types such as CommandSubject, ListSubject, DictionarySubject, ViewModel, ObservableDynamicObject, Either<TLeft, TRight>, Maybe<T> and others.
- Various interactive labs that illustrate the runtime behavior of the extensions in Rxx. Individual labs' source code included.
The latest release of Rxx is now available:
New features for Rxx 1.2 include:
- Compatible with Microsoft's Ix Experimental library.
- UI extensions for WPF and Silverlight, including AnonymousCommand, CommandSubject, a Subscription XAML markup extension for binding UI elements to observables, EventSubscription trigger and a reactive view model infrastructure. (Download the labs application for examples.)
- N-ary Zip and CombineLatest combinators.
- Several parser updates, including new operators, non-greedy (lazy) quantifiers and major performance and memory improvements, such as avoiding stack overflows due to recursion in quantifiers.
- Cursor types and extensions (Rx and Ix).
- ListSubject and DictionarySubject.
- Consume extensions that generalize the producer/consumer pattern over observables.
- ApplicationSettingsBase extensions.
- ObservableSyndication for RSS 2.0 and Atom 1.0.
- ObservableFile and additional ObservableDirectory extensions.
- Stream, FileStream and TextReader extensions.
