You need to ensure that the service publishes the WSDL description at http://services.contoso.com/OrderLookupService.svc?wsdl.

<serviceDebug includeExceptionDetailInFaults=”true” />
B.

<serviceDiscovery>
<announcementEndpoints>
<endpoint name=”wsdlAnnouncement” kind=”udpAnnouncementEndpoint” />

</serviceDiscovery>
C.
Insert the following element at line 06.
<serviceMetadata httpGetEnabled=”true” />
D.

<serviceMetadata httpGetEnabled=”false” />
Explanation:
<serviceMetadata>
(http://msdn.microsoft.com/en-us/library/ms731317.aspx)httpGetEnabled A Boolean value that specifies whether to publish service metadata for retrieval using an HTTP/Get request.
The default is false. If the httpGetUrl attribute is not specified, the address at which the metadata is published
is the service address plus a “?wsdl”. For example, if the service address is “http://localhost:8080/CalculatorService”,
the HTTP/Get metadata address is “http://localhost:8080/CalculatorService?wsdl”.
If this property is false, or the address of the service is not based on HTTP or HTTPS, ?wsdl is ignored.
