The module contained in the DevExpress.ExpressApp.Validation.Win.v20.2.dll assembly.

The ValidationWindowsFormsModule module creates validation error messages (invoked after rules are broken) that are more informative and user friendly than default exception messages. Additionally, this module provides in-place validation support (see IModelValidationContext.AllowInplaceValidation). To add this module, invoke the Application Designer for the WinForms application and drag the ValidationWindowsFormsModule item from the Toolbox to the Modules panel.
