Vista - cannot resolve symbol ' datacontract'

Im designing a service using vs 2005

I have made a interface using ServiceContract....
no problem

Then i try to add some data contracts

using System;
using System.Collections.Generic;
using System.Text;
using IECServer.Datatypes;

namespace IECServer.Request {
[DataContract(Namespace="somenamespace")]
public class MyData {
[DataMember]
public string Name;
[DataMember]
public int? ID;
[DataMember]
public DateTime StartDate;
}
}

But visual studio flags an error saying
cannot resolve symbol ' DataContract'
and the same for DataMembers
This ofcause results in a non compilable code

MessageContracts works fine too....

I have installed
.. net 3.0
orcas

Anyone got a idea why.

I'm not familiar with the error codes in C#, but for VB I believe you are
getting the "[objectname] is not defined".

In your Using statements you need to be using some more namespaces....
ServiceContract is defined under the System.ServiceModel namespace (must add
reference to this assembly to the project)... and DataContract/Member
classes are defined under System.Runtime.Serialization (I don't remember
whether you need to add a reference to the system.runtime.serialization
assembly).

Try adding those namespaces and see what happens - hope this helps! :-)

Did you try examples with DataContract from Platform SDK ? Just a hint

Thank you for your help.

I already had the referance added to the seviceModel, but the problem
was the
System.Runtime.Serialization module I was suppose to add. The book I
used just forgot to tell me that it was a seperate namespace for
DataContract.
