Help! I can't use a DataSet

Hi:

I have an ASP.NET project using C#.

When I try to declare a DataSet I get this error:
"c:\WINNT\Microsoft.NET\Framework\v1.1.4322\System .Data.dll Referenced class 'System.Data.DataSet' has base class or interface 'System.Xml.Serialization.IXmlSerializable' defined in an assembly that is not referenced. You must add a reference to assembly 'System.Xml'."

Even if I add:
using System.Xml it still gives me this error.

If I rem the declaration of the DataSet (below) the error goes away.

How can I solve this?

Code:

using System;
using System.Data;
using System.Data.SqlClient;
using System.Collections;

namespace MyApplication
{
    public class RptFunctions
    {
        private SvrFunctions oSvrFunc = new SvrFunctions();
        private  SqlConnection oCn;
        private  SqlParameter Parm;
        private  SqlCommand CMD;
        protected SqlDataAdapter Adp;    
        protected DataSet pdsCFMainSum;
 . . .
