The WPF app is developed strictly in MVVM pattern

Let's say I have a List included 3 items in ViewModel

var Items = new List<item> { Item1, Item2, Item3}
<ListView Margin="5,5,5,20" SelectionMode="Single"
	SelectedValue="{Binding SelectedItemObj}"
        IsSynchronizedWithCurrentItem="True" 
        ItemsSource="{Binding Items, Mode=OneWay}">


And the user click on the grid on Item2
So, the SelectedValue = Item2

A service async updated the Items collection at seperate thread by

Items[1] = NewItem;

Because of that, the SelectedValue in the ListView is lost
And one of the side note is that the async update is very frequentPlease hope if there's

anyone who can suggest a solution for me

Million Thanks
