title: Enum not serializing
body: <p>I have a WCF service.
  it is bound to an MSMQ but that is not the issue here.
  I can serialize an object which has a base class and an interface implemented in the base class and the concrete class derives from the base class - this works fine.</p>
  
  <p>however, when I have an enum in the base class and I set that value, then after it being deserialized/read from the MSMQ, that value is still set to the default value (i.e not the one set manually in code)</p>
  
  <p>any ideas whats going on? I even marked the enum as a DataContract and also each of the Enum members with an EnumMember attribute.</p>
  
  <p>how can I serialize enums?</p>
