FluentValidation 2.0 RC1 is now available for download.

The biggest change in this release is the addition of the WithLocalizedName method which supports localizing only the name portion of a validation message (previously, you would have to override the entire message if you wanted it to use custom resources).

Summary of changes since 2.0 beta 2:

• Updated MVC integration to work with MVC3 RC2
• Allow custom MVC ModelValidators to be added to the FluentValidationModelValidatorProvider
• Support using a resource provider for custom property validators through the new IResourceAccessorBuilder interface
• Added WithLocalizedName as a counterpart to WithLocalizedMessage
• Deprecated the WithPropertyName method as it was misleading. Depending on your scenario, you should either use WithName or OverridePropertyName instead.
• Renamed IErrorMessageSource and its derivatives to IStringSource (breaking change)

All changes since 1.3:

• Removed the v1.1 backwards compatibility layer. If you’re still using old-style custom validators (which were marked as Obsolete since v1.2), you will need to upgrade.
• Silverlight assembly renamed to FluentValidation.dll for consistency (formerly was FluentValidation.Silverlight.dll)
• Provide more useful information in ValidationException error message.
• Removed old mechanism for specifying cascade mode. Use .Cascade(cascadeMode) instead
• FluentValidatorModelMetadataProvider now converts NotNull/NotEmpty validators to IsRequired in metadata.
• Patch – updated German localization
• Using a child validator on a collection will now skip items in the collection that are null.
• NotEmptyValidator can now work against empty collections (for collections that implement ICollection)
• Performance improvements to AttributedValidatorFactory
• Fixed an issue where CascadeMode values are ignored if they’re changed after the rules have been defined.
• Ported FluentValidation to WP7.
• ShouldHaveChildValidator test helper now works with child collection validators
• Simplified the implementation of SetValidator.
