## ListBoxItem IsSelected binding issue with ObservableCollection<T>.Move

### Scope
Minor

### Version Introduced
4.5

### Version Reverted
4.6

### Source Analyzer Status
Planned

### Change Description

Calling <xref:System.Collections.ObjectModel.ObservableCollection`1.Move(System.Int32,System.Int32)>
or
<xref:System.Collections.ObjectModel.ObservableCollection`1.MoveItem(System.Int32,System.Int32)>
on a collection bound to a
<xref:System.Windows.Controls.ListBox?displayProperty=name> with items selected
can lead to erratic behavior with future selection or unselection of
<xref:System.Windows.Controls.ListBox?displayProperty=name> items.

- [ ] Quirked
- [ ] Build-time break

### Recommended Action

Calling <xref:System.Collections.ObjectModel.Collection`1.Remove(`0)?displayProperty=name>
and
<xref:System.Collections.ObjectModel.Collection`1.Insert(System.Int32,`0)?displayProperty=name>
instead of
<xref:System.Collections.ObjectModel.ObservableCollection`1.Move(System.Int32,System.Int32)>
will work around this issue. Alternatively, this issue has been fixed in the
.NET Framework 4.6 and may be addressed by upgrading to that version of the .NET
Framework.

### Affected APIs
* ``M:System.Collections.ObjectModel.ObservableCollection`1.Move(System.Int32,System.Int32)``
* ``M:System.Collections.ObjectModel.ObservableCollection`1.MoveItem(System.Int32,System.Int32)``
