• .NET Core Version: 5.0

• Have you experienced this same bug with .NET Framework?: Yes

Problem description:

• If to set SupportsUiaProviders as true for any control it will lose LegacyIAccessiblePattern implementation. In this case, you can't set accessible Role, Name, and other properties for this control.

Expected behavior:

• All control accessible objects support LegacyIAccessiblePattern

Minimal repro:

• Create a .Net 5.0 Winforms app
• Add a control, which supports uia provider
• Try to set AccessibleName or AccessibleRole
• Run Inspect and look at LegacyIAccessible properties
