Hello.
I tried to use a .NET 5 application written using WinForms:
https://github.com/Greavesy1899/MafiaToolkit

After I close the intro window, this exception happens:

System.EntryPointNotFoundException: Unable to find an entry point named
'UiaDisconnectProvider' in DLL 'UIAutomationCore.dll'.
   at Interop.UiaCore.UiaDisconnectProvider(IRawElementProviderSimple provider)
   at System.Windows.Forms.Control.ReleaseUiaProvider(IntPtr handle)
   at System.Windows.Forms.Control.WmDestroy(Message& m)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at System.Windows.Forms.ButtonBase.WndProc(Message& m)
   at System.Windows.Forms.Button.WndProc(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, WM msg, IntPtr
wparam, IntPtr lparam)

Apparently, it tries to unregister a UI Automation provider on window
destruction.

MSDN docs:
https://docs.microsoft.com/ru-ru/windows/win32/api/uiautomationcoreapi/nf-uiautomationcoreapi-uiadisconnectprovider?redirectedfrom=MSDN

Since current uia_core implementation is largely stub, I think it might benefit
from one more stub ;)
