Namespace:   System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public bool Enabled { get; set; }

Property Value

Type: System.Boolean

true if the reliable session is enabled; otherwise, false. The default value depends on the binding being used.

The ability to enable a reliable session is provided with three of the system-provided bindings. A reliable session is:

The following example shows how to create a new reliable session, access and change the default values of that session.

private void Run()
    WSHttpBinding b = new WSHttpBinding();
    b.Name = "HttpOrderedReliableSessionBinding";

    // Get a reference to the OptionalreliableSession object of the 
    // binding and set its properties to new values.
    OptionalReliableSession myReliableSession = b.ReliableSession;
    myReliableSession.Enabled = true; // The default is false.
    myReliableSession.Ordered = false; // The default is true. 
    myReliableSession.InactivityTimeout = 
        new TimeSpan(0, 15, 0); // The default is 10 minutes.
    // Create a URI for the service's base address.
    Uri baseAddress = new Uri("http://localhost:8008/Calculator");

    // Create a service host.
    ServiceHost sh = new ServiceHost(typeof(Calculator), baseAddress);

    // Optional: Print out the binding information. 
    // Create a URI for an endpoint, then add a service endpoint using the
    // binding with the latered OptionalReliableSession settings.
    sh.AddServiceEndpoint(typeof(ICalculator), b, "ReliableCalculator");



private void PrintBindingInfo(WSHttpBinding b)
    Console.WriteLine("Enabled: {0}", b.ReliableSession.Enabled);
    Console.WriteLine("Ordered: {0}", b.ReliableSession.Ordered);
    Console.WriteLine("Inactivity in Minutes: {0}",
