Generate Sample SOAP Request from WSDL

[Marc J. Cawood]

Is it possible in .NET to generate a sample SOAP request as an XML
string given a WSDL at runtime? Basically for making a program similar
to XMLSpy, OxygenXml or the following:

http://wscep.sourceforge.net/createrequest.html

I've seen many samples (e.g. WCF Dynamic Proxy) for generating dynamic
proxies but no way to get at the outgoing SOAP Request as an XML
Document or string.

The simplest version is surely an XSL template which transforms the
WSDL I imagine...
