PollingDuplexHttpBinding Constructor (PollingDuplexMode)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Initializes a new instance of the PollingDuplexHttpBinding class with a specified mode of behavior on the server in response to client polling.

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

Syntax

'Declaration
Public Sub New ( _
    duplexMode As PollingDuplexMode _
)

public PollingDuplexHttpBinding(
    PollingDuplexMode duplexMode
)

Parameters

duplexMode
Type: System.ServiceModel.Channels.PollingDuplexMode
The mode of behavior exhibited on a server in response to client polling when the communication between them is configured for duplex polling.

Remarks

Use this constructor if you want to use a non-default value for the duplex mode. The default value used by the default constructor for the PollingDuplexMode is SingleMessagesPerPoll(), which indicates that the server will return one message every time the client polls for a message and then close the polling connection.

This constructor uses a default value for the security mode. The default value used for the PollingDuplexHttpSecurityMode is None, which specifies that the SOAP message is not secured and the client is not authenticated.
