Question

I get this:

An error occurred while receiving the HTTP response to http://localhost:8732/Design_Time_Addresses/PersistencyService/Service1/. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

Why do I get this? I assume it is because the method takes about 1 min to complete. How can disable any time limit?

I get this when running in VS a Windows form project that uses a WCF service in the same solution

My WCF configuration:

<system.serviceModel>
   <bindings>
      <wsHttpBinding>
        <binding name="LongRunning" sendTimeout="00:10:00" />
      </wsHttpBinding>
   </bindings>
   <client>
      <endpoint name="Default"          
                address="http://localhost:8732/Design_Time_Addresses/PersistencyService/Service1/"         
                binding="wsHttpBinding"                    
                bindingConfiguration="LongRunning"
                contract="PersistencyService.IService1" />
   </client>
   <services>
      <service name="PersistencyService.Service1">
         <endpoint 
             address="" 
             binding="wsHttpBinding"  bindingConfiguration=""
             contract="PersistencyService.IService1" >
             <identity>
                <dns value="localhost" />
             </identity>
         </endpoint>
         <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
         <host>
            <baseAddresses>
               <add baseAddress="http://localhost:8732/Design_Time_Addresses/PersistencyService/Service1/" />
            </baseAddresses>
         </host>
      </service>
   </services>
   <behaviors>
      <serviceBehaviors>
         <behavior>
            <serviceMetadata httpGetEnabled="True"/>
            <serviceDebug includeExceptionDetailInFaults="False"/>
        </behavior>
      </serviceBehaviors>
   </behaviors>
</system.serviceModel>

The exception message is An existing connection was forcibly closed by the remote host.
I must also add that I get about 70MB of data from the service

On the client side, you need to add some settings to your app.config:

<system.serviceModel>
   <bindings>
      <wsHttpBinding>
         <binding name="LongRunning" sendTimeout="00:10:00" />
      </wsHttpBinding>
   </bindings>
   <client>
       <endpoint name="Default"
           address="....."
           binding="wsHttpBinding"
           bindingConfiguration="LongRunning"
           contract="IYourServiceContract" />
   </client>
</system.serviceModel>

You didn’t give us much to go on – no config, nothing…. so I’m left just guessing what settings you might have.

Basically, you need to define a binding configuration for the type of binding you’re using, and you need to increase the sendTimeout attribute on that binding configuration (here in my sample: 10 minutes). You cannot completely turn off the timeout – you can increase it, but not turn it off.

Then, your client side config must make a reference to that binding configuration you’ve defined, by specifying a bindingConfiguration="...." attribute on the <endpoint> configuration, and using the same name for the binding configuration as when you defined it.

Maybe this is enough – but maybe, you’ll also need to increase some of the timeouts on the server side. Try this first – if it doesn’t work, come back and ask again – and please, next time: provide us with some more useful info, like your code and config!
