<para>This interface enables data entity classes to implement custom validation rules and expose validation results asynchronously. This interface also supports custom error objects, multiple errors per property, cross-property errors, and entity-level errors. Cross-property errors are errors that affect multiple properties. You can associate these errors with one or all of the affected properties, or you can treat them as entity-level errors. Entity-level errors are errors that either affect multiple properties or affect the entire entity without affecting a particular property.</para>

<para>This property returns false if there are no known entity-level or property-level validation errors for the entity at the time it is accessed. However, some validation rules may still be running asynchronously as described for the <see cref="M:System.ComponentModel.INotifyDataErrorInfo.GetErrors(System.String)" /> method. </para>
