Answer
Metadata Providers supply display names, validation rules, formatting, and UI hints. They influence model binding, validation, scaffolding, and Tag Helpers, ensuring consistent UI rules across apps.
Quick Answer
Metadata Providers (IDisplayMetadataProvider, IValidationMetadataProvider) feed metadata about model properties to the view rendering pipeline — display names, data type hints, validation error messages. Tag helpers like asp-for use this metadata to generate correct HTML attributes. Implement a custom provider to centralize display/validation metadata outside DataAnnotations.
