En el ejemplo siguiente se muestra cómo configurar un servicio para usar el NetMsmqBinding enlace.

En primer lugar, el archivo de configuración.

A continuación, el código de servicio real.

    void Multiply(double n1, double n2);
    [OperationContract(IsOneWay = true)]
    void Divide(double n1, double n2);

Comentarios

El NetMsmqBinding enlace proporciona compatibilidad con la puesta en cola mediante Message Queuing (MSMQ) como transporte y permite la compatibilidad con aplicaciones acopladas de forma flexible, aislamiento de errores, operaciones de nivelación de carga y desconectadas. Para obtener una explicación de estas características, consulte Información general sobre colas.

Se trata de uno de los enlaces proporcionados por el sistema proporcionados por Windows Communication Foundation (WCF). El procedimiento recomendado es definir el enlace mediante valores de configuración y no usar un enfoque basado en código, excepto en determinados escenarios avanzados en los que se deben establecer valores de configuración como servicio.
