ReactiveUI 4.5 is Released

Download the binaries for all platforms

What’s New

Xamarin.iOS and Xamarin.Mac support

This release brings initial support for the latest Xamarin.Mac and Xamarin.iOS. Using ReactiveUI and Xamarin Studio, you can write cross-platform ViewModels and Model classes and bind them to Views using the same RxUI 4.x binding syntax.

  • ReactiveUI knows how to bind to Cocoa objects using Key-Value Observing
  • DeferredScheduler automatically runs code on the Cocoa main runloop
  • Routing and ViewModelViewHost is supported via a class that attaches to NSView
  • Command binding understands Cocoa controls via Cocoa target/action framework, including automatically disabling the control when CanExecute is false
  • Many common controls have implicit binding support

Caveat Emptor

There’s one hack that you have to do on iOS, due to assembly loading working differently. Put in the following lines in your AppDelegate.cs:


(new ReactiveUI.Xaml.ServiceLocationRegistration()).Register();
(new ReactiveUI.Routing.ServiceLocationRegistration()).Register();
(new ReactiveUI.Cocoa.ServiceLocationRegistration()).Register();

Experimental Xamarin.Android support

This release also includes very basic Xamarin.Android support, including a scheduler that will run code on the Activity’s main thread.

What do I need to run this??

You need to run Xamarin Studio and make sure to have the latest updates installed from the Alpha Channel.

What else is New?

  • Bug fixes in UserError Handling
  • Extra documentation (thanks @ArturPhilibin!)
  • Add Debugger support for ReactiveCollection (#204, thanks @distantcam!)
