mono-reactive aims to provide Reactive Extension (Rx) [*1] features to the Mono world. Right now it is almost about System.Reactive.dll implementation, but I'm looking forward to seeing it running ReativeUI [*2] for iOS as well as Mono for Android support. System.Reactive.dll is feature complete, but there is a couple of things that are known to fail. Also I'm still newbie in Rx land, there are likely stupid implementation and nasty hacks. Patches, bug reports and/or any feedback are welcome. [*1] http://msdn.microsoft.com/en-us/library/hh242985.aspx [*2] http://www.reactiveui.net/ Atsushi Eno (@atsushi_eno / @atsushieno)
