If you want to handle each change event with Rx, you can monitor it with the following method by combining it with [R3](https://github.com/Cysharp/R3):
```csharp
Observable<CollectionAddEvent<T>> IObservableCollection<T>.ObserveAdd()
Observable<CollectionRemoveEvent<T>> IObservableCollection<T>.ObserveRemove()
Observable<CollectionReplaceEvent<T>> IObservableCollection<T>.ObserveReplace()
Observable<CollectionMoveEvent<T>> IObservableCollection<T>.ObserveMove()
Observable<CollectionResetEvent<T>> IObservableCollection<T>.ObserveReset()
```

The basic idea behind using ObservableCollections is to create a View. In order to automate this pipeline, the view can be sortable, filtered, and have side effects on the values when they are changed.

Reactive Extensions with R3
---
Once the R3 extension package is installed, you can subscribe to `ObserveAdd`, `ObserveRemove`, `ObserveReplace`, `ObserveMove`, and `ObserveReset` events as Rx, allowing you to compose events individually.
PM> Install-Package [ObservableCollections.R3](https://www.nuget.org/packages/ObservableCollections.R3)
```csharp
using R3;
using ObservableCollections;
var list = new ObservableList<int>();
list.ObserveAdd()
.Subscribe(x =>
{
Console.WriteLine(x);
});
list.Add(10);
list.Add(20);
list.AddRange(new[] { 10, 20, 30 });
```
Since it is not supported by dotnet/reactive, please use the Rx library [R3](https://github.com/Cysharp/R3).
Blazor Blazor

Since Blazor re-renders the whole thing by StateHasChanged, you may think that Observable collections are unnecessary. However, when you split it into Components, it is beneficial for Component confidence to detect the change and change its own State.

In Unity projects, you can installing `ObservableCollections` with [NugetForUnity](https://github.com/GlitchEnzo/NuGetForUnity). If R3 integration is required, similarly install `ObservableCollections.R3` via NuGetForUnity.
