[DOTNET] SOAP Problems with ASP.NET

[Tewari, Vijay]

I am sending the following explicitly using sockets to a ASP.NET service

POST /HelloWorldService/Service1.asmx HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://tempuri.org/Add";
Content-Length: 544
Expect: 100-continue
Connection: Keep-Alive
Host: localhost

<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:types="http://tempuri.org/encodedTypes"; xmlns:tns="http://tempuri.org";
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";><SOAP-ENV
:Body><tns:Add><a xsi:type="xsd:int">70</a><b
xsi:type="xsd:int">89</b></tns:Add></SOAP-ENV:Body></SOAP-ENV:Envelope>


I have been confounded by the response
