I'm trying to create a SOAP web service and web client in C# without using the WCF tools. My objective is to create a client that communicates with a SOAP service that most likely is not using WCF. I made a proof of concept client, but at the moment I'm not really sure how to write the raw SOAP XML to send to the WCF service to test my client. Also, can I use WCF on the client side even if the SOAP service does not use WCF? Thanks!

wr.Headers.Add("SOAPAction", soapMessage.SoapAction);
wr.Credentials = soapMessage.Credentials;
wr.Method = "POST";
wr.GetRequestStream().Write(Encoding.UTF8.GetBytes(soapMessage.ContentXml), 0, soapMessage.ContentXml.Length);
