The following web service is run by Perl:

#!perl -w
use SOAP::Lite +trace => "debug";
print SOAP::Lite
->uri("urn:WebServices")
->proxy("http://example.com")
->SomeMethodName('param1', 'param2')
->result;

But since Perl doesnt support autogenerated wsdl and no one bothered to
write the wsdl Im unable to run the wsdl.exe tool to get the classes
needed.

How can I consume a web service when there is no wsdl file to use?

I need to use this web service as part of a C# application.
