A validation provider provides validation logic for the data model. A validation provider must derive from ModelValidatorProvider. You can inherit from this class if you want to use a custom validator provider or a third-party validator that uses attribute-based metadata. This class performs most of the work that is required in order to implement the ModelValidatorProvider class.

When you implement this class, use the AssociatedMetadataProvider class to implement the metadata provider.

Model provider classes and validator provider classes are loosely coupled. Therefore, they work independently, and have no dependencies on each other.

However, the metadata provider exposes metadata that can be accessed and used by validation providers. For example, the MVC default metadata provider (the DataAnnotationsModelMetadataProvider class) reads the display name of an object, and the display name is used by the DataAnnotationsModelValidatorProvider validation provider when it creates a validation error message.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
