Hi all
Really need some help or enlightenment on how to solve this problem have
followed the example on msdn but can't seem to get the SoapExtensiontype to
work in the web.config keep getting a "can't parse or it can't find the file
when I try to run the web service
1 Extension Code copied from MSDN :(traceSoap example)
Imports System
Imports System.Web.Services

Namespace TraceSoapExtension
' Define a SOAP Extension that traces the SOAP request and SOAP response
' for the XML Web service method the SOAP extension is applied to.
Public Class TraceExtension

Private oldStream As Stream
Private newStream As Stream
Private m_filename As String
' Save the Stream representing the SOAP request or SOAP response into
' a local memory buffer.
Public Overrides Function ChainStream(ByVal stream As Stream) As
Stream
oldStream = stream
newStream = New MemoryStream()
Return newStream
End Function
' When the SOAP extension is accessed for the first time, the XML Web
' service method it is applied to is accessed to store the file
' name passed in, using the corresponding SoapExtensionAttribute.
Public Overloads Overrides Function GetInitializer(ByVal methodInfo

' instead of an attribute applied to a specific XML Web service
' method. Return a file name based on the class implementing the Web

2. My WS Code
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Namespace Users
<WebService(Namespace:="http://tempuri.org/";)> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Public Class Service
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function HelloWorld() As String
Return "Hello World"
End Function
End Class
End Namespace
3. the Web config entry to so that ASP find and can inst.
<webServices>
<soapExtensionTypes>
<add type="TraceSoapExtension.TraceExtension, Users"
priority="1"
group="High"/>
</soapExtensionTypes>
</webServices>
Error I get is
