Hi guys,

The DataAnnotations attributes appear to only localizable messages if they come from a resource file compiled into the web application.

We use a custom resource provider ( setup from the system.web/globalization configuration element ) so we can have consistent messaging across all our applications, so we don't have to recompile for every typo and allow us to add new languages in 1 go.

Is this possible, if not, then how do I accomplish this ?

The DataAnnotations attributes are not tied to ASP.NET, so they have no knowledge of (and cannot participate in) the specialized ASP.NET resource system. You must use a traditional embedded string resource (with the auto-generated class wrapper) with DataAnnotations attributes.
