using Proto buf in WCF

Step 1: download Protobuf and ref in prj , url :
http://code.google.com/p/protobuf-net/

Step 2: Simply change DataContract -> ProtoContract
DataMember -> Protomember (orderNo)

 
[ProtoContract]
    public class CompositeType
    {
        bool boolValue = true;
        string stringValue = "Hello ";
 
        [ProtoMember(1)]
        public bool BoolValue
        {
            get { return boolValue; }
            set { boolValue = value; }
        }
 
        [ProtoMember(2)]
        public string StringValue
        {
            get { return stringValue; }
            set { stringValue = value; }
        }
    }
