WCF service for Silverlight application returns “NotFound”

Question

I have a WCF web service for a silverlight application that doesn't seem to want to work.

Pretty straight forward; when I debug the silverlight application and wcf at the same time, just after launching the WCF stops working and throws the following message:

CommunicationException was unhandled by user code. The remote server returned an error: NotFound.

The WCF references another code library named DAL which uses SubSonic and stores a database file I'm working with.

Here is my WCF web.config file. There seems to be something wrong because there's no endpoints in it but I'm not entirely sure.

<?xml version="1.0"?>
<configuration>
  <connectionStrings>
    <add name="Database" connectionString='Data Source=.\SQLEXPRESS;AttachDbFilename="[FILE LOCATION OF MDF FILE]";Integrated Security=True;User Instance=True' providerName="System.Data.SqlClient" />
  </connectionStrings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
  <modules runAllManagedModulesForAllRequests="true"/>
 </system.webServer>
</configuration>

Any help would be much appreciated.

Thanks

In debugging this type of problem I typically use Fiddler (http://fiddler2.com/fiddler2/) to capture the actual response from WCF, which should give you much more detail about the problem since the NotFound message that SL gets hides the actual exception.
