How to configure WCF timeouts? - wcf

Question

I have a test WCF application that simply calls a method on the service layer. I am trying to test WCF timeouts but I can't seem to get the timeout to occur - I've added a thread sleep to simulate a long-running transaction.
I have set the sendTimeout="00:05:00" in the client binding configuration but this doesn't seem to have any affect when I add a 15 second thread sleep in the service call. i.e. the application waits 15 seconds and the result is successfully returned.
Client Configuration
<configuration>
<system.serviceModel>
<bindings>
<ws2007HttpBinding>
<binding name="WS2007HttpBinding_IBookService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:05:00" sendTimeout="00:05:00"
bypassProxyOnLocal="false" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
useDefaultWebProxy="true" allowCookies="false">
<security>
<transport realm="" />
</security>
</binding>
</ws2007HttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8080/bookservice/ws" binding="ws2007HttpBinding"
bindingConfiguration="WS2007HttpBinding_IBookService" contract="BookServiceReference.IBookService"
name="WS2007HttpBinding_IBookService" />
</client>
</system.serviceModel>
</configuration>

How do I get the timeout to occur?

Answer 1

Well 15 seconds is certainly less than 5 minutes (that is the value of sendTimeout="00:05:00").
If you want to simulate a sendTimeout violation which would raise a TimeoutException then you need to guarantee that the service call will not return until after the sendTimeout has been exceeded.
In your particular situation of 5 minutes then this will suffice:
public int MyServiceCall()
{
// Better bring something to read...
System.Threading.Thread.Sleep(300000);
return 0;
}
