Examples

The following example shows how to configure a service to use the NetMsmqBinding binding.

First, the configuration file.

Next, the actual service code.

// Define a service contract.
[ServiceContract(Namespace="http://Microsoft.ServiceModel.Samples")]
public interface IQueueCalculator
{
    [OperationContract(IsOneWay=true)]
    void Add(double n1, double n2);
    [OperationContract(IsOneWay = true)]
    void Subtract(double n1, double n2);
    [OperationContract(IsOneWay = true)]
    void Multiply(double n1, double n2);
    [OperationContract(IsOneWay = true)]
    void Divide(double n1, double n2);
}

' Define a service contract.

    Sub Multiply(ByVal n1 As Double, ByVal n2 As Double)
    <OperationContract(IsOneWay := True)> _
    Sub Divide(ByVal n1 As Double, ByVal n2 As Double)
End Interface

Remarks

The NetMsmqBinding binding provides support for queuing by using Message Queuing (MSMQ) as a transport and enables support for loosely-coupled applications, failure isolation, load leveling and disconnected operations. For a discussion of these features, see Queues Overview.

This is one of the system-provided bindings provided by Windows Communication Foundation (WCF). The recommended procedure is to define the binding using configuration values and not to use a code-based approach, except in certain advanced scenarios where configuration values must be set as a service is initialized.

Constructors

NetMsmqBinding()	Initializes a new instance of the NetMsmqBinding class.
NetMsmqBinding(NetMsmqSecurityMode)	Initializes a new instance of the NetMsmqBinding class using the specified security mode.
NetMsmqBinding(String)	Initializes a new instance of the NetMsmqBinding class from the settings of a specified configuration binding element.
