A Quick Primer on Namespace Bindings

Add or remove SOAP 1.2 for ASMX services

ASMX 2.0 supports both SOAP 1.1 and SOAP 1.2.  But how do you use SOAP 1.2 with your ASMX services?  Suppose you have a web service using ASMX 2.0 and you want to explicitly consume a SOAP 1.2 web service.  The documentation for adding or removing SOAP 1.2 support in a web service doesn’t seem up-to-sync yet. … Read more
