Changes in 7.0:

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 - see https://github.com/JeremySkinner/FluentValidation/wiki/l.-Strong-naming-and-signed-packages

  • 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
