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

public TimeSpan InactivityTimeout { get; set; }

Property Value

Type: System.TimeSpan
The TimeSpan value that specifies the maximum interval of time that can pass without activity on a channel before the channel enters a faulted state.


The value is less than zero, or it is larger than the maximum time allowed.

Activity in this context is defined as completed sends or messages being queued for receive.

If a channel has received a CloseSession message from the remote endpoint, the channel is in a half-closed state in which it can still send messages. As a consequence, if Send calls are the only remaining activity, the channel faults when an InactivityTimeout() interval of time passes after the last Send call.

PollingDuplexHttpBinding pollingDuplexBinding = new PollingDuplexHttpBinding();
BindingElementCollection bindingEC = pollingDuplexBinding.CreateBindingElements();
//Check on binding elements contained in the collection
bool boolHTBE = bindingEC.Contains(typeof(HttpTransportBindingElement));
//Returns true
string txtboolHTBE = boolHTBE.ToString();
bool boolHSTBE = bindingEC.Contains(typeof(HttpsTransportBindingElement));
//Returns false
string txtboolHSTBE = boolHSTBE.ToString();
