Please read the upgrade notes at https://fluentvalidation.net/upgrading-to-8 Changes in 8.1: * Add format support in message placeholders. * Added support for overriding indexers for collection rules. * Allow error codes to be used to override localization key in the Language Manager. * Additional error details are now shown in the ShouldNotHaveValidationErrorFor test extension. * Conditions defined with root-level When/WhenAsync/Unless/UnlessAsync are now only executed once (instead of once for each rule). * Support Otherwise method chained from root-level When/WhenAsync/Unless/UnlessAsync. * Minor wording changes to default English error messages. Changes in 8.0: * Support validating only specific properties by path. * Added OnFailure method * Deprecated RuleFor(..).SetCollectionValidator in favour of RuleForEach(...).SetValidator * IStringSource.GetString now takes a validation context instead of a model instance. * Introduce PropertyValidatorOptions in order to clean up the IPropretyValidator interface. * Moved the legacy ValidatorAttribute and AttributedValidatorFactory into a separate FluentValidation.Attributes package. * Remove the pre-7.0 localization mechanism * Remove the pre-7.0 methods for custom validation * Removed many other deprecated methods Full release notes can be found at https://github.com/JeremySkinner/FluentValidation/blob/master/Changelog.txt
