When using this class, messages serialized on the wire are unwrapped, unless the data is a message contract type or of type [System.ServiceModel.Channels.Message].

The following example shows how to use a SendMessageContent instance with a Send activity.

Variable<PurchaseOrder> po = new Variable<PurchaseOrder>();
Variable<Customer> customer = new Variable<Customer>();

Endpoint clientEndpoint = new Endpoint
{
    Binding = Constants.Binding,
    AddressUri = new Uri(Constants.ServiceAddress)
};

Send submitPO = new Send
{
    Endpoint = clientEndpoint,
    ServiceContractName = Constants.POContractName,
    OperationName = Constants.SubmitPOName,
    Content = new SendMessageContent(new InArgument<PurchaseOrder>(po))               
};
