title: How to pass any object as parameter to WCF service?
body: <p>I've got the the following interface method:</p>
  
  <pre><code>[OperationContract]
  void AddObject(object o);
  </code></pre>
  
  <p>Of course this won't work because 'o' can't be deserialized on the service side. Is there any way around this? Maybe by putting the types in the web.config? Like the user of the service can define the types he'd like to pass to this method.</p>
  
  <p>Thanks</p>
