Gets or sets the version of the SOAP protocol used to make the SOAP request to the XML Web service.
Assembly: System.Web.Services (in System.Web.Services.dll)
The property is set in the proxy class generated by the Web Services Description Language tool (Wsdl.exe) to Soap11 by default when a WSDL document for an XML Web service supports SOAP version 1.1. However, when an XML Web service only supports SOAP 1.2, Wsdl.exe sets the property to Soap12. To choose the version of the SOAP protocol when generating the proxy class with Wsdl.exe, use the /protocol switch with the SOAP or SOAP12 settings to set the property to Soap11 and Soap12, respectively.
