Need some help for new starters

Hi,

I'm thinking about to use ReactiveUI to develop a WPF app, but i never use both before. Should I learn WPF first or just look into the RxUI examples. I used to develop win form apps use C# a lot by the way.

Thanks a lot for seeing this.

In my opinion, learning MVVM and ReactiveUI at the same time would be a bit to swallow, because you're actually learning four things: (1) WPF; (2) the MVVM pattern; (3) reactive programming in general; and (4) ReactiveUI specifically.

That said, one of the reasons I like ReactiveUI is that it allows you to start simple and grow. (I'm still mostly at simple, for what it's worth.) You can start by using ReactiveUI the same way that you would use any MVVM framework, and don't have to learn or even touch the reactive pieces of it at first. Just use the nice little shortcuts it provides: let your ViewModels inherit from ReactiveObject (or ReactiveValidatedObject if you need validations), use this.RaiseAndSetIfChanged() and perhaps an occasional this.WhenAny(), but otherwise don't bother with all the complicated stuff about observables - at least, until you're comfortable with WPF and MVVM.

Hope this helps.

I agree with Ken, trying to apply ReactiveUI without having background in MVVM in WPF (assuming this is the case) would be a bit difficult.

In my opinion, you should start grasping the fundamentals of the MVVM pattern and applying that in WPF. I think that is essential to effectively use ReactiveUI (or any other frameworks for that matter) in WPF/Silverlight/WP/Win8.

Thank you! That makes it clear to me.

Though you also won't suffer any ill-effects if you just make your ViewModel classes inherit from ReactiveObject . . . you'll get some nice shortcut methods and can worry about the rest later.
