If you're really using Windows Forms, why are you trying to use a WebForms control? The two frameworks are not compatible.

For Windows Forms validation, you need to use the Windows Forms tools:
ErrorProvider Component - Windows Forms .NET Framework | Microsoft Learn[^]
User input validation - Windows Forms .NET | Microsoft Learn[^]
