Why does Sharepoint 2010 Web Reference work, but Service Reference does not
- by Darien Ford
Sharepoint is setup to use NTLM authentication.
When I reference http://myserver/Sites/Ops/_vti_bin/Lists.asmx?WSDL as a Web Reference, I can call the methods and get valid responses.
When I reference the same url as a Service Reference, the server throws an exception when calling methods.
My account is admin on the Sharepoint Farm.
This is the app.config for the service reference (mostly auto generated):
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="ListsSoap" closeTimeout="00:01:00" openTimeout="00:01:00"
receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://myserver/Sites/Ops/_vti_bin/Lists.asmx"
binding="basicHttpBinding" bindingConfiguration="ListsSoap"
contract="SharepointLists.ListsSoap" name="ListsSoap" />
</client>
</system.serviceModel>
</configuration>
Saddly, the only information the exception provides is this:
"Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown."
No other details.
The code that I'm using is:
public ListClass()
{
_Client = new SharepointLists.ListsSoapClient();
}
public System.Xml.Linq.XElement GetTaskList()
{
return _Client.GetList("Tasks");
}
Any thoughts? I would like to use the Service Reference rather than the Web Reference.
UPDATE:
I tried Rob's suggestion and got this error:
HTTP GET Error
URI: http://myserver/Sites/Ops/_vti_bin/Lists.asmx
The document at the url http://myserver/Sites/Ops/_vti_bin/Lists.asmx
was not recognized as a known document type.
The error message from each known type may help you fix the problem:
- Report from 'http://myserver/Sites/Ops/_vti_bin/Lists.asmx' is 'The document
format is not recognized (the content type is 'text/html;
charset=utf-8').'.
- Report from 'DISCO Document' is 'There was an error downloading
'http://myserver/_vti_bin/Lists.asmx?disco'.'.
- The request failed with HTTP status 404: Not Found.
- Report from 'WSDL Document' is 'The document format is not recognized
(the con
tent type is 'text/html; charset=utf-8').'.
- Report from 'XML Schema' is 'The document format is not recognized (the
