title: WCF enums, What if I don't mark members as EnumMember?
body: <pre><code>[DataContract]
  public enum Color
  {
      Red,
      Blue
  }
  
  [DataContract]
  public enum Color1
  {
      [EnumMember]
      Red,
      [EnumMember]
      Blue
  }
  </code></pre>
  
  <p>will this two enums treated differently when serializing, or at client side?</p>
