Add Web Service Reference fails

I'm trying to connect a SAP soap provider with a C# program...

@Edit: SAP on it's non-public webservice provider, prompts for user and password (before anything)

Using the info here:

I came to the webservice I have to attach to, and when user/password prompted, I've placed it. ~~However I think I've written the password wrong~~ (See EDIT II down below), because the soap response is this one:

- <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
- <soap:Body>
- <soap:Fault>
  <faultcode>soap:Server</faultcode> 
  <faultstring>No binding data for configuration key: "005056AA63891ED480C5CC2F714805E3"</faultstring> 
- <detail xmlns:slibfault="http://xml.sap.com/2005/11/esi/slib/fault/">
  <slibfault:timestamp>Tue, 15 Jul 2014 16:01:21 GMT</slibfault:timestamp> 
- <slibfault:exception>
  <slibfault:text>No binding data for configuration key: "005056AA63891ED480C5CC2F714805E3"</slibfault:text> 
  <slibfault:position program="CL_SRT_WSP_WSDL_HANDLER=======CP" include="CL_SRT_WSP_WSDL_HANDLER=======CM00K" line="82" /> 
  </slibfault:exception>
  </detail>
  </soap:Fault>
  </soap:Body>
  </soap:Envelope>

Now, User and Password aren't prompted, as if a "Remind My Password" checkbox were checked.

~~Is there any way to refresh the "Visual Studio WebService cache" or something?~~

@EDIT II: I've tried twice now (by adding it to another project with the same results) and it's not problem that the passwd has been miswritten, the pass is correct, but the reference builder keeps showing this.

WebServices Found at this URL:

There was an error downloading 'http://fooserver:8000/sap/bc/srt/wsdl/srvc_005056AA63891ED480C5CC2F714805E3/wsdl11/allinone/ws_policy/document?sap-client=400/_vti_bin/ListData.svc/$metadata'.
The request failed with the error message:
--
<soap:Envelope xmlns:soap="http://s

Any Ideas?

Solution

When this response is the one you receive from SAP, it means the service exposed has been deprecated.

I cannot explain what is happening from the SAP side, (since I'm a C# dev), but What I do can tell you is that the SAP side is intentionally (manual abap developer handling) not expecting further communications from clients.

So... ask your ABAPer on your SAP side, he may have done something with the service you where trying to connect to, since it's no longer available.

You can also verify that by going to the wsdl page "manually" by placing it in the browser. You'll see the same XML response.

@Icing-on-the-cake Edit: If you encounter the issue that credentials is somewhat stored/cached by .Net, simply

go to the Solution Panel,
left click on the project on which you tried to add the reference
and select unload project.

Afterwards repeat that but to Load that same project.

That will "refresh" the credentials "stored".
