Ejemplos

En el ejemplo siguiente se requiere que CalculatorService use un WSHttpBinding objeto con entrega de mensajes ordenada. Las sesiones confiables y la entrega en cola no se usan de forma predeterminada con este enlace, pero se pueden habilitar.

<!-- Here is the configuration for a CalculatorService using a WSHttpBinding with ordered message delivery required. -->
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <system.serviceModel>
      <services>
         <service
             type="Microsoft.ServiceModel.Samples.CalculatorService">
            <!-- Use base address provided by host and a WSHttpBinding named "Binding1" -->
            <endpoint address=""
                      binding="wsHttpBinding"
                      bindingConfiguration="Binding1"
                      contract="Microsoft.ServiceModel.Samples.ICalculator" />
         </service>
      </services>

      <bindings>
         <wsHttpBinding>
            <binding name="Binding1">
               <!-- The next element enables a ReliableSession and required ordered delivery-->
      <reliableSession enabled="true" ordered="true"/>
      </binding>
         </wsHttpBinding>
      </bindings>

   </system.serviceModel>
</configuration>

// The CalculatorService configuration has enabled a reliable session
// with ordered delivery set to true. This means that the binding
// requirement for ordered delivery specified by the
// BindingRequirementsAttribute on the CalculatorService class
// implemented below will be satisfied by this WSHttpBinding.

Comentarios

La IBindingDeliveryCapabilities interfaz debe implementarse mediante un enlace si los clientes y servicios deben poder estipular, como parte de su contrato, que el enlace proporciona las características que requieren.
