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);
}

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.

Properties

MaxReceivedMessageSize	Gets or sets the maximum size, in bytes, for a message that is processed by this binding. (Inherited from MsmqBindingBase)
MaxRetryCycles	Gets or sets the maximum number of retry cycles to attempt delivery of messages to the receiving application. (Inherited from MsmqBindingBase)

ReceiveRetryCount	Gets or sets the maximum number of immediate delivery attempts on a message that is read from the application queue. (Inherited from MsmqBindingBase)
ReceiveTimeout	Gets or sets the interval of time that a connection can remain inactive, during which no application messages are received, before it is dropped. (Inherited from Binding)
RetryCycleDelay	Gets or sets a value that indicates the time delay between retry cycles when attempting to deliver a message that cannot be delivered immediately. (Inherited from MsmqBindingBase)
Scheme	Returns the scheme for this binding. (Inherited from MsmqBindingBase)
