Add support for ASP.NET Core 3.1 Fixed issue with property indexers being incorrectly stripped out when using test extensions. AddToModelState no longer includes a dot if PropertyName is null

Ensure lazily loaded calls to WithMessage can be used for client-side validation, provided they don't attempt to access model properties from inside the delegate (eg when using IStringLocalizer). Fix issue where OnFailure didn't work properly when invoked on validators with conditions.

Add ASP.NET Core-compatible version of the email address validator. Simplify the advanced testhelper syntax. Add support for ASP.NET Core 3. Add support for defining child rules inline. ValidatorDescriptor now has consistent handling of model-level rules. RuleForEach can now access collection index in error message with {CollectionIndex} placeholder. Welsh language translations of default error messages. Hungrian language translations of default error messages. Indonesian language translations of default error messages. Using RuleForEach combined with When is now more intuitive. Fixed order of rule execution when using async validation.

Added simplified version of several messages across all translations to aid with ASP.NET Clientside validation. New enum validator for string properties.

Fix issue in ASP.NET Core integration with GetServiceProvider not working correctly when invoked against a CustomContext/MessageBuilderContext. Improved how LanguageStringSource works with error-code overrides. Fix thread-safety issue with use of PropertyValidatorOptions.Empty (now removed). Improved how calls to When/Unless are handled internally. DelegatingValidator is now marked as deprecated. Improvements to Croatian language translations. Improvements to Georgian language translations. Resolved subtle bug where top-level WhenAsync wouldn't work correctly when wrapping a top-level call to When.

Fix the same issue from 8.1.1 but for async conditions. Fix issue where shared When/Unless conditions didn't execute correctly when used with RuleForEach.

Added RuleSetsExecuted property to ValidationResult. Fix issue with shared condition cache incorrectly caching when used with RuleForEach.

Added format support for message placeholders. Added support for overriding indexers for collection rules. Allow ErrorCode 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.

Added AbstractValidator.PreValidate to allow immediate cancellation of validation.

Using [BindProperty] in AspNetCore now works when implicit child validation is disabled. ShouldHaveChildValidator now works when the child validator is inside a DependentRules block. Test helpers are now compatible with custom property name resolvers set using ValidatorOptions.PropertyNameResolver. Switched to embedded debug symbols.

Fixed a regression where calling ValidateAsync with RuleForEach would no longer execute tasks sequentially (#799).

Added support for RuleForEach to the testing extensions (#238). Fixed a regression where calling ValidateAsync with RuleForEach could cause a deadlock (#799).
