Bindable LINQ libraries or "why Obtics is not actively maintained anymore"

Question

The ultimate task is: bind some WPF controls to LINQ queries.

Having searched for "Bindable LINQ" I've found multiple references to Obtics, Bindable Linq and Continuous LINQ. They do what I want to, but one thing confuses me: their age. Seems like their development stopped at nearly the same time somewhere in 2009-2010, which is suspicious.

Is it still reasonable to use them? Haven't they eventually been superseded by some standard library means?

Answer 1

After some more research:

1. I've found OLinq. It is maintained and quite functional. Some Linq operations are missing, but it's fairly expandable by design.
2. I haven't seen any mentions of how good or bad such a solution is. Looks like it's simply uncommon.

Answer 2

Let me introduce my library ObservableComputations. It is production ready library sutable for bind WPF controls to LINQ like queries.

Answer 3

What you are looking for are Reactive Extensions (Rx.Net). For working with WPF MVVM there´s a library called ReactiveUI.

Then you can use ReactiveList instead of ObservableCollection and just define your linq querys on that list.

code form their documentation:

DocumentList = new ReactiveList<Document>() {
    ChangeTrackingEnabled = true,
};

DocumentList.ItemChanged
    .Where(x => x.PropertyName == "IsDirty" && x.Sender.IsDirty)
    .Select(x => x.Sender)
    .Subscribe(x => {
        Console.WriteLine("Make sure to save {0}!", x.DocumentName);
    });
