[ObservableLookup] implementation

[xperiandri]

I need an ObservableLookup which implements ILookup<TKey, TValue> interface? Can I contribute it or will you implement it?

[neuecc]

I think ILookup is readonly so no observable.

[xperiandri]

Even though it is read-only our lookup class can be mutable. The main point is that it has to work like an ObservableDictionary storing ObservableCollections as values

[neuecc]

Value changes not be monitoring other types either.

[xperiandri]

I have not gotten your point

[xperiandri]

This is what I implemented

https://github.com/Ecierge/Elmish.Uno/tree/eCierge/src/Elmish.ObservableLookup

from this as a source

https://github.com/xamarin/Xamarin.PropertyEditing/blob/972186e6ddd68566375da7bc336e566196f44307/Xamarin.PropertyEditing/ObservableLookup.cs

[xperiandri]

Can we port that to you?

[xperiandri]

What do you think?

[neuecc]

From what I see, you are still adding a mutable type called IMutableLookup, right?

[xperiandri]

In my sample, I do. However, it is not mandatory

[xperiandri]

Any thoughts?

[neuecc]

not positive.
