asp.net - Log both webservice Request, Response in SoapExtension -

i using soapextension log both webservice request, response when error occurs in webservice. both request , response xmldocument's have incorrect data. can review code see doing wrong? if unable centralize changes in soapextension, go adding logging code around each webservice endpoint.

solved removing "static" property xmlrequest, xmlresponse properties. "xmlresponse" during "soapmessagestage.afterserialize" process , "xmlrequest" during "soapmessagestage.beforeserialize" process. had switched.
