Validation Framework for a WPF app (using MVP) and ASP.NET MVC

Question

I'm looking for a form validation framework that works best in both Windows (WPF using MVP) and Web (ASP.NET MVC).

I'm currently looking at three choices:

• Enterprise Library Validation Application Block
• http://www.codeplex.com/FluentValidation
• http://validationframework.codeplex.com

I like Fluent Validation as it looks a lot cleaner. The others, though, have been around longer.

Any other recommendations?

In MVC apps I've found Fluent Validation very useful for more complex validations. DataAnnotations are often enough for simple validations in MVC.
