exram / exram.reactivecollections Goto Github PK

Is there a nuget package for this project? If not, could you please create one?

A while back, I created a similar project called MuVaViMo (https://github.com/Yeah69/MuVaViMo) and it works well for simple use cases. However, at that time I wasn't into Reactive Extensions and did create the project without it. Since I discovered Rx I thought that Rx would be an improvement, but hadn't managed to spare enough time to refactor and extend my project.
Consindering the description of your project I think that ExRam.ReactiveCollections is far ahead of my project. Hence, I would like to test your project as replacement for MuVaViMo.

I would love to see an example on how to use the collections. For example how to replace a .Scan<>(ImmutableDictionary<>) with that.
Maybe in the Readme in a second section.

I cannot get the ObservableCollection aspect to work (LINQPad script):

var list = new ListReactiveCollectionSource<int>();
var rc = list.ReactiveCollection;
var oc = rc.ToObservableCollection();
for (var i = 0; i < 10; i++)
{
	await Task.Delay(TimeSpan.FromSeconds(0.2));
	list.Add(i);
}
list.Count.Dump("ListReactiveCollectionSource.Count");
oc.Count.Dump("ObservableCollection.Count");

The script dumps

ListReactiveCollectionSource.Count
10
ObservableCollection.Count
0

I was expecting the oc.Count to be updated when the source collection was changed. I see now that a property changed event seems to be emited for the Count property when the source collection changes - it's just that the property does not store any value which seems a bit misleading.
