In the Orchestration View window, expand the top node of the tree view (this node will have the same type name as the orchestration) so that the Messages folder is visible. Right-click the Messages folder, and select New Message, which creates a message. Click the new message, and give it a descriptive name in the Properties window. In this example, the message is named incomingOrder. Click the Message Type property in the Properties window, and select the .NET type System.Xml.XmlDocument. From the toolbox, drag a Receive shape onto the orchestration directly beneath the green circle at the top of the design surface. With the Receive shape selected, specify the shape s Name, Message, and Activate properties. In our example, we use ReceiveOrder, incomingOrder (created in step 3), and True, respectively.
