Inside of a service method, how do I know where the message was delivered? Without defining what distinguishes a location it's hard to explain where 'here' is. I've got a few guesses though based on the most common variations of this question: OperationContext.Current.IncomingMessageHeaders.To

Reading Messages for Validation

How do I perform XML validation against an entire message? There is a method to read the body of the message but it's only possible to read headers one at a time. Although it sounds more complicated than it really is, a straightforward way to read an

Printing Flexible Message Headers

When a message header supports multiple representations, which version is used when the message header is printed? A message header is a piece of data about the message that's carried on the wire somewhere apart from the message contents. When using an

Body is a Stream

I've answered this question before but it continues to keep being asked so I'll answer it again. This comes up most often when someone is trying to log messages, either through the official message logging feature or on their own by calling ToString.

Reader Quotas with Untyped Messages

I have an operation contract that uses untyped messages. When using the message, I get an error telling me to change the quota settings on the XmlReader. Where are these quotas located? I'm not using an XmlReader. A message represents an XML InfoSet.
