Symptoms
When you try to use a Microsoft Visual Studio .NET 2003 client application against a Microsoft SQL Server 2005 native Web service,a System.InvalidOperationException exception may occur.
Resolution
This problem occurs because the System.Data.DataSet object that Visual Studio .NET 2003 uses does not support the XML Schema definition language (XSD) schemas that SQL Server 2005 generates.
