||
|
|
### Change Description

In the .NET Framework 4.5, WPF Selector properties (such as 'SelectedItem' on ListBoxes or DataGrids) that are data-bound to static properties do not properly update when their bound property is updated.

### Recommended Action

This behavior was reverted in a servicing update for the .NET Framework 4.5. Please update the .NET Framework 4.5, or upgrade to .NET Framework 4.5.1 or later, to fix this issue.

### Notes
|
||
|
|
We could look for FrameworkElement.SetBinding calls, but this is such a corner case of that (selected properties and static properties) that it would probably be too noisy. A xaml analyzer is probably our best bet, and that's not even going to be perfect
