Reactive programming (RP) is based on data flows and the propagation of change, with the underlying execution model of a programming language automatically propagating changes through the data flow. With the popularity of event-driven, scalable, and interactive architectures both on the server and the client, the concept of “reactiveness” is increasingly gaining attention.
Ian Griffiths has published a six part series on when to use, and when not to use, .NET 4.5’s async features with WPF. The series begins with a post titled Too Much, Too Fast with WPF and Async.
Reactive Extensions (Rx) has been open sourced by Microsoft Open Technologies. This increases the chances that it will be available with Mono soon as well.
Reactive Extensions 2.0 RC is out and it now supports .NET 4.0 (except few features) along with 4.5. It also has several improvements in the way it deals with time.
The new functionality in .NET 4.5 with it the opportunity to revisit the out of band libraries such as Reactive Extensions. Bart De Smet talks about what’s in the Rx experimental branch.
Richard Szalay is demonstrates how Reactive Extensions can be used to make asynchronous testing with the Silverlight Unit Testing Framework less error prone.
Interactive Extensions (Ix) is a set of additional LINQ to Objects query operators based on the work done in the Reactive Extensions. A quick look through the API reveals a set of IEnumerable extension methods under the System.Linq namespace. While most developers already have many of these in their own utility libraries, having a standard implementation for these missing features would be useful.
Microsoft has released version 1.0 of their Reactive Extensions (Rx) library after two years in incubation. Rx combines event-driven UI with LINQ, concurrency and asynchronous calls.
A new preview of TPL Dataflow has recently been released along with Visual Studio Async. Along with performance enhancements and stronger ties with the Reactive Framework, it is being positioned as a foundation for building actor/agent style frameworks as opposed to a complete solution.
