• Text(Xml) Message Encoder(به صورت پیش فرض در تمام Http-Base Binding‌ها از این Encoder استفاده می‌شود)
  
• Binary Message Encoder(به صورت پیش فرض در تمام Net* Binding‌ها از این encoder استفاده می‌شود که برای سرویس‌های وب مناسب نیست)
• MTOM Message Encoder (در حالت استفاده از Http-Base Binding‌ها و انتقال اطلاعات به صورت باینری از این گزینه استفاده می‌شود که به صورت پیش فرض غیر فعال است)

[MessageContract]
public class MyFile
{
    [MessageHeader] 
    public String Filename { get; set; }

    [MessageBodyMember]    
    public Byte[] Contents { get; set; } 
}

• به جای DataContract از MessageContract استفاده می‌شود؛
• تمام خاصیت هایی که نوع آن‌ها غیر از []Byte است باید دارای MessageHeader باشند؛
• خاصیتی که برای انتقال محتوای باینری تهیه شده است، باید از MessageBodyMember استفاده نماید؛
• مجاز به تعریف فیلد یا فیلد هایی که نوع آن‌ها Primitive Type است نمی‌باشید.
  

تنظیمات مربوط به Binding نیز به صورت خواهد بود:

<bindings> 
    <wsHttpBinding>
        <binding name="WsHttpMtomBinding" messageEncoding="Mtom" /> 
    </wsHttpBinding>
 </bindings>
