Gets or sets a value that indicates whether the Formatter property value is used to deserialize the request message.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Use the property to control whether the formatter deserializes the return value from an inbound message or whether the inbound message is returned directly as the return value. If the value is false, the return type must be of type Message and there can be no out parameters, otherwise an InvalidCastException is thrown at run-time.
