When binding a Object that implements INotifyCollectionChanged to a ItemsControl, update the object doesn't trigger view updating about avalonia HOT 5 CLOSED

INCC needs to be on the UI thread. Using their ObservableList<T> works fine. It's only an issue with the INotifyCollectionChangedSynchronizedView<T>. Their WPF sample shows using BindingOperations.EnableCollectionSynchronization, so not being on the UI thread seems to be a possible scenario. I would have expected an exception or log message on Verbose, but I don't seem to get either.

I saw it, but I don't need to synchronize across thread (at least not right now), so I thought this is optional. ObservableList<T> don't have INCC, so INotifyCollectionChangedSynchronizedView<T> is the only option here if I want to keep using this.

Can you please file a minimum sample? I'll not explore a random file renamer as that could be harmful to my machine.

Hi, this name "DumbRenamer" is a project I just started, despite the solution name, there is not much code, and not much going on, that's why I upload it, and it's without any dll or built binary.

But I understand your concern. Here are the some sample code files in a zip (.cs file and .axaml files are not directly allowed somehow)

PS: CommunityToolkit.Mvvm package and ObservableCollections package from "https://github.com/Cysharp/ObservableCollections" are required.

You need the Dispather if you update things from a Task.

private async Task ChangeValue()
{
    await Task.Delay(1000);
    Dispatcher.UiThread.Post(() => { TestInt = 10 });
    ExecutePreview();
}
