Description

Describe the problem

Hi all, it would be nice to have an option to use DataGrid's SelectedItems in MVVM pattern also for setting selected items programatically, simillar to CollectionView in Xamarin. Now it is read only IList.

Describe the solution

Publish SelectedItems as ObservableCollection or some other type implementing some of observable patterns.
