Let's expand on the example we looked at in Chapter 1, Hello BizTalk Services. If you recall, this example received a file via SFTP and routed it to a Service Bus endpoint. Now we'll add a map to the solution. The map will transform the incoming message into a different format expected by the recipient. However, as noted previously, if we're to turn one message format into another, we need to define the schema of the target message first in order for us to be able to map to it.

Now, right-click on the project and navigate to Add | New Item. Select Map from the list of items and provide the name...
