As you most likely are aware, when a BizTalk Server adapter receives a document, it generates a BizTalk message. Documents obtained by BizTalk are included in the news, along with the message context. BizTalk Server uses the message context to store various properties when processing the document. There are three properties in the Message Context: name, namespace, and value.

The BizTalk Server adds message context properties to each message as it passes through.

• Result from extracting data from the message, for example, the order ID or the tracking number
• Or added by pipelines and adapters at the receiving end, for example, transport name or receive port name

There are mainly two benefits of this context.

• To provide the various components of BizTalk with easy access to these properties without having to parse the message
• To support content-based routing
