Answer
Metadata Providers supply display names, formatting rules, validation metadata, and UI hints for binding, validation, scaffolding, and rendering.
Quick Answer
Metadata providers (IDisplayMetadataProvider, IValidationMetadataProvider) supply metadata about model properties to MVC — display names, validation messages, data type hints. They're used by Razor Tag Helpers and HTML Helpers to generate form fields with correct labels and error messages. Custom providers let you centralize display logic instead of scattering DataAnnotations everywhere.
