FluentValidation 7.0 is a major release that contains several breaking changes, especially with Localization. If you use FluentValidation's support for localization please read the updated documentation: https://github.com/JeremySkinner/FluentValidation/wiki/f.-Localization * Localization rewrite to not require satellite assemblies * New 'Custom' rule method replaces the root-level Custom method * Switch to Netstandard based build process * Assemblies are now signed / strongly named * Fix - Possible NullReferenceException in the AspNetCore clientside integration for length validators * Fix - Don't clear the ModelValidatorProviders collection by default in the AspNetCore integration (added new ClearValidatorProviders property to control this behaviour) * Fix - Ensure IValidatorFactory is resolved from request scope in asp.net core integration * Fix - Property getter that throws an exception causes validation to fail in WebApi integration * Fix - Issue in AspNetCore integration where we tried to resolve a collection validator in some situations where a class validator should be used * Fix - Incorrect clientside validation attributes generated for email validator and credit card validator in the asp.net core integration * Fix - Child model validation now works in webapi integration * Improve splitting of PascalCased property names to support uppercase character sequences * ValidationResult.ErrorCode property now always returns the type of the PropertyValidator that generated the message, unless it's been explicitly overriden * Additional overload of WithState allows access to collection item when used with RuleForEach Full release notes can be found at https://github.com/JeremySkinner/FluentValidation/blob/master/Changelog.txt
