Missing 'System.Runtime.Serialization' and 'System.ServiceModel'

I am getting following errors when creating WCF data contract in service factory.
"The type or namespace name 'DataMemberAttribute' does not exist in the namespace 'System.Runtime.Serialization' (are you missing an assembly reference?)"

I tried adding a reference of 'System.Runtime.Serialization' but could not find it under .net tab. The similar error I am getting for 'System.ServiceModel'.

I have visula studio 2005 with SP1 running on windows xp professional version 2002 with SP2. Is there any patch do I need to install in order to get those missing files.
Please help.
