AvaloniaList<T> or ObservableCollection<T> 's Move Method can not refresh ui

[lishuangquan1987]

when I write the below code:
var index = this.Vo.SubConfigs.IndexOf(this.SelectedSubConfig); this.Vo.SubConfigs.Move(index, index + 1);
the ui can not change the element order,SubConfigs is AvaloniaList<T>,When I change SubConfigs to ObservableCollection<T> type , the ui can not refresh yet,stay the same.
Does anyone have the same problem?

Which thread are you on? Only the UI thread should ever update the collection.
