How to consume multiple WCF services from one client

Question

I am still learning the whole WCF thing, so please bear with me here.

What I have is two self hosted services created using C# and VS 2008:
Service # 1 Adds two numbers and returns the result.
Service # 2 Returns the square of a number.

I want the client to be able to send in two numbers to Service 1, get the sum and then send the sum in to Service 2 and get the square.

I have two generated proxies for both the services, and I am able to use Intellisense on them, so that part supposedly works.

Now how do i configure my app.config file such that I can communicate with both the services? Right now, i get an exception every time I try to do that.

[The client works fine if I only have one of the configurations in the app file at a time, and try to call only that server.]

I suppose this is a very noobish question, and the answer probably is "structure the config file in _____ manner", but Google simply does not seem to have an example/guide.

Anyone know how to do this?

Note: Consume multiple WCF services from one client client Though sounds like a duplicate is NOT what I am looking for.

Edit: Thanks to marc_s, I got it working

With both the services running in different apps, I did not need to split the server config file, but here is what I did with the client config files: First auto-generated the config files using SvrUtil.exe and then merged them in this way:

<bindings>
  <wsHttpBinding>

    <binding>
    ...
    </binding>

    <binding>
    ...
    </binding>

  </wsHttpBinding>
</bindings>

...

  <endpoint>

...

I realise you have asked for an App.Config answer but figure this might help. I would normally start by configuring the client connections programatically first, since it's simpler, and once you have got that working you could move it to your App.Config.

Here's an exmaple of how to configure a WCF client.

BasicHttpBinding binding = new BasicHttpBinding();
EndpointAddress address = new EndpointAddress(serverURL);
MyServiceClient myServiceProxy = new MyServiceClient(binding, address);

You could then have something like the below in your App.Config.

<client>
    <endpoint address="http://localhost/service1.asmx"
            binding="basicHttpBinding"
            bindingConfiguration="basicHttpBinding" 
            contract="IService1"
            name="Service1" />
    <endpoint address="http://localhost/service2.asmx" 
            binding="basicHttpBinding"
            bindingConfiguration="basicHttpBinding"
            contract="IService2"
            name="Service2" />
</client>
