Increasing the timeout value in a WCF service

Question

Hi,

How do I increase the default timeout to larger than 1 minute on a WCF service?

Answer 1

Are you referring to the server side or the client side?

For a client, you would want to adjust the sendTimeout attribute of a binding element. For a service, you would want to adjust the receiveTimeout attribute of a binding elemnent.

<system.serviceModel>
  <bindings>
    <netTcpBinding>
    <binding name="longTimeoutBinding"
        receiveTimeout="00:10:00" sendTimeout="00:10:00">
      <security mode="None"/>
    </binding>
    </netTcpBinding>
   </bindings>

  <services>
    <service name ="longTimeoutService"
      behaviorConfiguration="longTimeoutBehavior">
      <endpoint address="net.tcp://localhost/longtimeout/"
        binding="netTcpBinding" bindingConfiguration="longTimeoutBinding">

      </endpoint>
    </service>
....

Of course, you have to map your desired endpoint to that particular binding.

Under the Tools menu in Visual Studio 2008 (or 2005 if you have the right WCF stuff installed) there is an options called 'WCF Service Configuration Editor'.

From there you can change the binding options for both the client and the services, one of these options will be for time-outs.

Different timeouts mean different things. When you're working on the client.. you're probably looking mostly at the SendTimeout - check this reference - wonderful and relevant explanation: http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/84551e45-19a2-4d0d-bcc0-516a4041943d/
