proxy class generated from svcutil.exe is not working in .net 2.0
===

I have to use a wcf service in the ssis script component which is developing in BIDS 2005. For this i have generated the proxy class of that service. After attaching the proxy class in the script component it has error of some class such as `System.Runtime.Serialization.DataContractAttribute` is not defined. Any suggestion how can i resolve this issue.. Or can wsdl is used to genrate proxy class of wcf service. so that it can be used in the .net 2.0.
