hello
i'm quite new to web services and i tryied to learn by following a 
walkthrough in the Microsoft documentation.

I created the simplest web service....with the Hello world method...and 
then tryied to web reference it from the simplest windows app ...
in the web reference dialog i typed the url to the web service...it 
located it..displayed in the left :

<?xml version="1.0" encoding="utf-8" ?> 
- <dynamicDiscovery xmlns="urn:schemas-dynamicdiscovery:disco.2000-03-17">
  <exclude path="_vti_cnf" /> 
  <exclude path="_vti_pvt" /> 
  <exclude path="_vti_log" /> 
  <exclude path="_vti_script" /> 
  <exclude path="_vti_txt" /> 
  <exclude path="Web References" /> 
  </dynamicDiscovery>


and in the right:


Web Services 
 
(none) 
No Web References were found on this page. 
Click for help on finding a Web Reference. 
 
 
Errors 
 
The document was not recognized as a known document type (WSDL, XML 
Schema, or Discovery document) for the following reason: 
  - The content type 'application/octet-stream' is not valid for an XML 
document.
 


in conclusion i can't add the reference....
this result had occured in every web service i used regardless how much 
complicated it was or not.
please help
