Setting a SendTimeout on the client-side binding should fix the problem, although it looks like the ServiceReferences.ClientConfig isn't correct, so is probably being ignored.  There's a sample ClientConfig in the Deployment\Snippets\Silverlight section of the Learning Resources, but here's one too -
 
<configuration>
  <system.serviceModel>
    <client>
      <endpoint name="EntityService"
                address="http://localhost:9009/EntityService.svc"
                binding="customBinding" bindingConfiguration="customBinaryBinding"
                contract="IdeaBlade.EntityModel.IEntityServiceContractAsync"
                />
      <endpoint name="EntityServer"
                address="http://localhost:9009/EntityServer.svc"
                binding="customBinding" bindingConfiguration="customBinaryBinding"
                contract="IdeaBlade.EntityModel.IEntityServerContractAsync"
                />
    </client>
    <bindings>
      <customBinding>
        <binding name="customBinaryBinding" sendTimeout="00:20:00">
          <binaryMessageEncoding/>
          <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
        </binding>
      </customBinding>
    </bindings>
  </system.serviceModel>
</configuration>

I have a class that implements an async behavior. When it runs, it times out after 2 minutes with the following error message:
IdeaBlade.EntityModel.EntityServerException occurred
Message="The HTTP request to 'http://localhost:9009/EntityServer.svc' has exceeded the allotted timeout. The time allotted to this operation may have been a portion of a longer timeout."
Cancelled=false

                 InnerException:


Here's the class: 

    public static class ContactAsyncBehaviors

    {

        public static void GetLotusNotesContactsAsync(string user, bool useRealEmail, AsyncCompletedCallback<InvokeServerMethodEventArgs> callback)

        {

            var manager = LocalEntityManager.DefaultManager;

            ServerMethodDelegate mydelegate = new ServerMethodDelegate(GetLotusNotesContacts);

            Guid myToken = Guid.NewGuid();

            manager.InvokeServerMethodAsync(mydelegate, callback, myToken, user, useRealEmail);

        }



        [AllowRpc]

        public static string GetLotusNotesContacts(IPrincipal principal, EntityManager em, params object[] args)

        {

            IService service = (IService)LocalUnityContainer.MainContainer.Resolve(typeof(IService), "LoadLotusNotesContacts");

            service.Execute((string)args[0], (bool)args[1]);

            return (string)service.ReturnValues[0];

        }

    }


The service is instantiated server-side through Unity and the service.Execute method takes a while to run. When the service.Execute is finished, the server-side GetLotusNotesContacts returns a status back to the client as a string.

My web.config says: 
<customBinding >

        <binding name="customBinaryBinding"  receiveTimeout="00:20:00" sendTimeout="00:20:00" openTimeout="00:20:00" closeTimeout="00:20:00" >

          <binaryMessageEncoding >

            <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"  />

          </binaryMessageEncoding>

          <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647"  />

        </binding>

      </customBinding>


and I added a ServiceReferences.ClientConfig that says: 
<system.serviceModel>



    <client>

<service name="EntityService" >

        <endpoint address=""   binding="customBinding" bindingConfiguration="customBinaryBinding" contract="IdeaBlade.EntityModel.IEntityServiceContract" />

      </service>

      <service name="IdeaBlade.EntityModel.Server.EntityServer">

        <endpoint address="" binding="customBinding" bindingConfiguration="customBinaryBinding" contract="IdeaBlade.EntityModel.IEntityServerContract" />

      </service>                

                

    </client>



    <bindings>

      <!--The default binding in the Silverlight app is http with binary encoding. 

          Max values are set here for testing; you should adjust to your application's requirements.

          If you modify the binding here, be sure to also create/modify the ServiceReferences.ClientConfig

          in the Silverlight application too.  Both the client and server sides must agree on

          the binding configuration in order for communications to succeed.

      -->

      <customBinding >

        <binding name="customBinaryBinding"  receiveTimeout="00:20:00" sendTimeout="00:20:00" openTimeout="00:20:00" closeTimeout="00:20:00" >

          <binaryMessageEncoding >

            <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"  />

          </binaryMessageEncoding>

          <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647"  />

        </binding>

      </customBinding>

    </bindings>

  </system.serviceModel>
