ASP.Net Class Library project accessing WCF

Existing Asp.Net project was consuming WCF WebService. Working OK.

I decided to move the business logic into a class library. So now the Class library consumes the WCF web service and the Asp.net app has no reference to it.

On the first call into the class Library by the Asp.net web app (debugging) I get an error:

Could not find default endpoint element that references contract 'CouponParking.ICouponService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I have stared at the Class library app.config (which was created by the IDE when I first added a Service reference to the WCF service) and it looks OK to me.

Assuming it needs altering could someone please cast a critical eye over it and tell me what needs doing. My understanding of endpoints is rudimentary.

The asp.net web.config does have an empty servicemodel section. I assume this is correct as the service reference has been removed.

The class library app.config follows then the WCF web.config so you can see the other end.

The WCF has an additional JSON endpoint because it is also consumed by an Android device.

App.Config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="SoapEndPoint" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:8707/CouponParking.svc/SOAP"
            binding="basicHttpBinding" bindingConfiguration="SoapEndPoint"
            contract="CouponParking.ICouponService" name="SoapEndPoint" />
    </client>
</system.serviceModel>
</configuration>

Web.Config:

Class libraries use the config file of their consuming application - they do not use their own. So you need to move the system.serviceModel portion from the library's app.congif to the web.config of the ASP.NET application:

<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding name="SoapEndPoint" />
    </basicHttpBinding>
  </bindings>
  <client>
    <endpoint address="http://localhost:8707/CouponParking.svc/SOAP"
              binding="basicHttpBinding" 
              bindingConfiguration="SoapEndPoint"
              contract="CouponParking.ICouponService" 
              name="SoapEndPoint" />
  </client>
</system.serviceModel>

Now when you call into the class library from the ASP.NET application, it should pick up the binding and the client endpoint.
