What do you mean when you say "a soap message template"? WSDL.EXE and
XSD.EXE will both generate .NET classes. When your web service receives a
message, it will be deserialized into an object of the appropriate class.
When that web method returns, it will serialize the return object into SOAP
and will send it:

<?xml version="1.0"?>

Running "wsdl /server" on this file will produce:

You can now create your webservice class by deriving from this:

public class MyExampleService : exampleService
{
public override Response MyOperation(Request Request)
{
Response response = new Response();
response.x = Request.x;
response.y = Request.y;
return response;
}
}


I hope that helps. I've left off details (and getting it to build) simply
because it's time for me to leave for work!
