The ComboBox in my app doesn't support the UI Automation (UIA) ExpandCollapse control pattern, and my customer using a screen reader isn't informed of the current state of the Combobox's dropdown, and isn't notified when the expanded state of the dropdown changes.
It is expected that in versions of .NET earlier than 4.7.1, the WinForms ComboBox does not support the UIA ExpandCollapse pattern. In .NET 4.7.1, the pattern is supported by the ComboBox.
To leverage the change introduced with .NET 4.7.1, either rebuild your app to target that version of .NET, or update your app's config file to specify that it should pick up the fix when .NET 4.7.1 is available on the machine, even if the app itself has not been rebuilt to target that version of .NET. More details on how the fix can be leveraged are at .NET Framework 4.7.1 Accessibility and WPF Improvements.
