 <p>You can create a <a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.modelvalidatorprovider%28v=vs.108%29.aspx" rel="nofollow"><code>ModelValidatorProvider</code></a> for Enterprise Library validation. Brad Wilson has a <a href="http://bradwilson.typepad.com/blog/2009/10/enterprise-library-validation-example-for-aspnet-mvc-2.html" rel="nofollow">blog post</a> describing how to do this.</p> <p>However, it looks like this will only perform server side validation. If the attributes you are using are very similar to DataAnnotations, I would recommend using them instead.</p>
