title: Data.Annotations with .NET 3.5
body: <p>I have a number of domain classes with DataAnnotations applied to them, and I require to validate them in my service layer.</p>
  
  <p>I am using WCF, .NET 3.5</p>
  
  <p>If i was using .NET 4 I would have access to the Validator as follows</p>
  
  <pre><code>Validator.ValidateObject(@event.Entity, new ValidationContext(@event.Entity, null, null), true); 
  </code></pre>
  
  <p>is there a framework in 3.5 which allows me to do the same?</p>
