Consuming SharePoint Web Services with WCF

I had a few problems getting the WCF config correct to call SharePoint web services so thought I would share the solution that worked for me:

ClientCredentials - client credentials are required

using (ListsSoapClient proxy = new ListsSoapClient())
{
    proxy.ClientCredentials.Windows.ClientCredential = new NetworkCredential();
    ...
}

Web.config or app.config - NTLM required

 <system.serviceModel>
  <bindings>
   <basicHttpBinding>
    <binding name="ListsSoap" maxReceivedMessageSize="9999999">
     <readerQuotas maxBytesPerRead="9999999"/>
     <security mode="TransportCredentialOnly">
      <transport clientCredentialType="Ntlm"/>
     </security>
    </binding>
   </basicHttpBinding>
  </bindings>
  <client>
   <endpoint address="http://corporate-portal.ccc/_vti_bin/Lists.asmx" binding="basicHttpBinding" bindingConfiguration="ListsSoap" contract="SPLists.ListsSoap" name="ListsSoap"/>
  </client>
 </system.serviceModel>
