title: Problem sharing domain model between WCF and Silverlight Project
body: <p>I am writing a Large Scale Silverlight Application.
  I am currently writing the data retrieval elements.</p>
  
  <p>I have now encoutered and issue.</p>
  
  <p>I have a common Project that hold objects, this project is referenced by both the UI and the WCF service.
  The UI requires INotifyPropertyChanged for binding purposes.</p>
  
  <p>Now the WCF must use the same objects, but I am getting a compiler error saying</p>
  
  <blockquote>
    <p>"The type
    'System.ComponentModel.INotifyPropertyChanged'
    is defined in an assembly that is not
    referenced."</p>
  </blockquote>
  
  <p>EDIT: The error is in the WCF service.</p>
  
  <p>I want one object class, how do I solve this problem?</p>
