  • Improved UIA peer logic.
  • Updated TreeListBox.InvalidateChildren to work properly for the root item when IsRootItemVisible is false.
  • Updated TreeListBox to not handle number pad arithmetic keys if focus is within an embedded TextBoxBase control.


  • Updated group dialog launcher buttons to report an appropriate name via UI automation properties.
  • Updated ScreenTip help text to wrap in scenarios where long localized strings cause it to extend past the ScreenTip width.
  • Fixed an issue where Backstage might not show properly when the Ribbon is in an interop scenario.

  • Fixed an issue where IntelliPrompt parameter info could flicker slightly while editing.
.NET Languages Add-on
