Get SOAP Message before sending it to the WebService in .NET

Question

I'm calling an external HTTPS webservice.

In order to check what is wrong, the owner needs the SOAP request I'm sending.

I have a web reference and the generated proxy class generated by VS 2008...

Is there a way to see the SOAP message just before sending it?

I'm thinking in some .net code... because the Sniffers I tried didn't "see" the webservice invocation don't know why.

What you need is a SoapExtension. There's quite a few good examples here:
