Validate data using DataAnnotations with WPF & Entity Framework?

Question

Is there any way to validate using DataAnnotations in WPF & Entity Framework?

Answer 1

I have written a Contributor based validator which includes a DataAnnotation validation contributor and also checks against broken bindings (where the user has entered incorrect type)
