Debugging a SOAPExtension in a web service client

[thatsMaBoy]

Hi,

I have a VB.NET 2003 web service client (EXE) that makes use of a
SOAPExtension class. The client calls a web service that returns a
SOAP message containing MIME encoded files. The SOAPExtension
intecepts the SOAP message and extracts the MIME, before passing on the
rest of the SOAP message to the client so it can process the remainder
of the data within the SOAP message.

My problem is that I have taken over the project from a colleague who
has left and I do not how to debug the low level code in the
SOAPExtension class. Whenever I place breakpoints in the SOAPExtension
class they are never hit. However, the breakpoints are always hit in
the webclient.vb class.

My solution consists of the following projects:

* "webclient" project - this contains:
1. "webclient.vb" (main VB code for the client)
2. "soapext.vb" - the SOAPExtension class VB code
3. .config files (i.e. webclient.exe.config)
4. In the references is a reference to MIMEHandler.DLL

* "MIMEHandler" project - this contains:
1. "soapext.vb"
2. References (to standard .NET system DLLS only)

* "Settings" project - this contains:
1. A settings form for the web client. On this form is a button for
invoking/calling the web service.
2. References (to standard .NET system DLLS only)

Please could someone tell me how to debug the SOAPExtension class. Do
I need to uninstall the web client (Add/Remove programs) and install it
using the .NET INSTALLUTIL utility? Is it better if I install the
client using INSTALLUTIL and then attach to the process? IS this
possible?? Help!!

Many thanks.
