FluentValidation 8.1.3
A validation library for .NET that uses a fluent interface to construct strongly-typed validation rules.
No packages depend on FluentValidation.
FluentValidation 8 is a major release. Please read the upgrade notes at https://fluentvalidation.net/upgrading-to-8
Changes in 8.1.3:
* Resolved issue where clientside validation was incorrectly generating metadata for rules with shared conditions.
* ScalePrecisionValidator now has a public method in the fluent interface.
* Fix placeholder names in ScalePrecisionValidator for consistency.
* Updates to Portuguese (Brazil) translations.
Changes in 8.1.2:
* Fix issue where shared When/Unless conditions didn't execute correctly when used with RuleForEach.
Changes in 8.1.1:
* Added RuleSetsExecuted property on ValidationResult.
* Resolved issue introduced in 8.1 where the shared condition cache does not work correctly with RuleForEach (#970).
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.
* Japanese translation of the default error messages.
* Added Skip property to MVC5's CustomizeValidatorAttribute for parity with AspNetCore and WebApi.
* Remove type constraint on the OverridePropertyName overload that takes an expression.
