For BizTalk Server to play a full role within the service bus, it must be able to not only expose service endpoints, but also easily consume them. Let's take a look at how to create an orchestration, which accepts messages through the WCF-NetTcp receive location created earlier and also calls a WCF service that reveals a single endpoint based on Named Pipes.
We start by adding a new orchestration file named LookupOrderContact.odx
to our existing BizTalk project in Visual Studio.NET. The orchestration starts up when a new order arrives. Therefore we should create a new orchestration message of type Seroter.BizTalkSOA.Chapter3.OrderManagement.BizTalk.NewOrder_XML
named NewOrder_Input
. After the order is received, we then call an existing WCF service, which provides us with more details about the customer placing the order. What do we need to know to call the WCF service from our orchestration? If you guessed the following, you'd be right:
