Now that I've covered several of the new feature additions in Orcas I also want to include mention of some of the fixes done to improve interoperability with other platforms. Allowing an empty SOAPAction. Previously we required that the HTTP SOAPAction header exactly match the addressing action. We now let you process messages with an empty SOAPAction as many other systems were processing messages based only on the addressing action. Handling empty messages that claim to be chunked. Previously we weren't able to process messages that said that they were chunked but didn't have any content. Some systems were transmitting every HTTP message as chunked (even the empty ones) so we now handle this case gracefully. Flexible content types. Previously we required that the character set parameter for an HTTP content type be the first parameter in the list. Some systems were generating content types with additional parameters in various orders so we've removed any dependency on the parameter order. Parsing MTOM includes. Previously we only supported the canonicalized format for the Include element of an MTOM message. Another system was generating MTOM messages where the elements were not canonicalized so we've added support to read those messages. Next time: Messaging Additions in Orcas, Part 4
