Using WCF Message Contracts in Operations

Typically when building Windows Communication Foundation (WCF) applications, developers pay close attention to the data structures and serialization issues and do not need to concern themselves with the messages in which the data is carried. For these applications, creating data contracts for the parameters or return values is straightforward. However, sometimes complete control over the structure of a SOAP message is just as important as control over its contents. This is especially true when interoperability is important or to specifically control security issues at the level of the message or message part. In these cases, you can create a message contract that enables you to use a type for a parameter or return value that serializes directly into the precise SOAP message that you need. This topic discusses how to use the various message contract attributes to create a specific message contract for your operation. Using Message Contracts in Operations WCF supports operations modeled on either the remote procedure call (RPC) style or the messaging style. In an RPC-style operation, you can use any serializable type, and you have available to you the features that are available to local calls, such as multiple parameters and ref and out parameters. In this style, the form of serialization chosen controls the structure of the data in the underlying messages, but the WCF runtime creates the messages themselves to support the operation. This enables developers who are not familiar with SOAP and SOAP messages to quickly and easily create and use service applications. The following code example shows a service operation modeled on the RPC style.
