title: WCF and XML Serializable issue
body: <p>I'm recieving an error in Traceviewer "To be XML serializable, types which inherit from IEnumerable must have an implementation of Add(System.Object) at all levels of their inheritance hierarchy. MySql.Data.MySqlClient.MySqlDataReader does not implement Add(System.Object)."</p>
  
  <p>I'm writing a WCF service that a sql query can be passed to it and will run the query.  Any idea what this error means? How to resolve the issue as well.</p>
  
  <p>This service is running Mysql Connector/Net as well</p>
