I have tried that to but as soon the program calls the webservice it throws
an exception about the anytype.

As anyone gotten a dataset with a Guid Field working from a webservice using
VS 2003?

Thanks

Hi,

I know but it does not work when I have a dataset that includes a table with
a uniqueidentifier field. The  xsd for the dataset looks like this:

<xs:element name="TestWeb">
 <xs:complexType>
   <xs:sequence>
      <xs:element name="ID" type="xs:int" />
      <xs:element name="Text1" type="xs:string" />
      <xs:element name="Text2" type="xs:string" />
      <xs:element minOccurs="0" name="Test3" type="xs:string" />
      <xs:element minOccurs="0" name="Text4" type="xs:string" />
      <xs:element msdata:DataType="System.Guid, mscorlib,        
          Version=2.0.3600.0,      Culture=neutral,  
          PubicKeyToken=b77a5c561934e089" minOccurs="0" name="Testuni"  
          type="xs:anyType" />  
     </xs:sequence>
  </xs:complexType>
</xs:element>

If I remove the uniqueidentifier field from the dataadaptor and re-generate
the dataset everything works. And I can refrence the web service with a
uniqueidentifier field from vs 2005 without any problem. I have also tried to
import the web service to a different mashine with VS2003 and have the same
problem.
