A client computer has the Microsoft .NET Framework 2.0 installed. You use the NetTcpBinding binding to connect the client computer to a Windows Communication Foundation (WCF) service. When the client computer receives a DataSet object from the WCF service, the set of values that is returned from the row.GetColumnsInError method is empty.
Note This problem does not occur when you use the wsHttpBinding binding to connect the client computer to the service.
