RFC: What are pain points with the ReactiveUI project as a user?

What are your pain points at the moment with RxUI?

Tell me and reply to this issue.

It would cool to see support for custom DI-containers, as everyone adheres to their favorite.

@nestquik See #14 about discussions how to approach that. Thanks for bringing it up.

UWP navigation...it's view-first and the way RxUI has implemented the VM-first approach has killed the niceness of the transition animations. It's currently just a flat-out hide/show approach.

Confusing threading exceptions when I referenced the ReactiveUI package in a WPF project without ReactiveUI.Wpf. That tripped me up at the first hurdle.

Coming from the perspective of the ReactiveUI book (which is great by the way), the first section says to just do an “Install-Package ReactiveUI”. The book mentions that the “bait and switch” technique should take care of the dependencies. However, doing this in a top-level WPF platform project is not enough. The nuget package targets System.Reactive (>= 4.0.0), but Glen mentioned that at the moment RxUI is using System.Reactive 3.1.1 and you need to add a reference to System.Reactive.Compatibility til the next release of RxUI. I’m new to this, but just getting started with the build configuration currently published is not straightforward at all (at least with respect to WPF). Diving into this great library more every day.

BTW ReactiveUI 8.4.1 was released this morning that has System.Reactive at 4.

The reasoning for the new ReactiveUI.WPF is Visual Studio for Mac unfortunately.

If you target the WPF platform you now need to install the WPF specific package otherwise schedulers won't be wired up and you'll be greeted with an appropriate exception. The documentation has been updated. We had to make this change prevent Visual Studio for Mac from exploding when it encountered an automatically imported reference to Windows.Presentation which prevented these folks from being able to unit test their applications with Visual Studio for Mac.

ReactiveUI v8.0.0 released

ReactiveUI is a composable, cross-platform model-view-viewmodel framework for all .NET platforms that is inspired by functional reactive programming which is a paradigm that allows you to express the idea around a feature in one readable place, abstract mutable state away from your user interfaces and improve improve the testability of your application.

Getting reactiveui/ReactiveUI#1598 shipped will help folks out heaps.
