title: WebService and database and user management
body: <p>I'm new to WebServices.<br>
  I want to create (very simple) WebService application with database (maybe MS-SQL) and user authentication (log in, log out) and some function that check is user is logged in before returning any result.<br>
  I found this <a href="http://www.codeproject.com/KB/cpp/WebServiceAuthentication.aspx" rel="nofollow">http://www.codeproject.com/KB/cpp/WebServiceAuthentication.aspx</a><br>
  I don't want anyone doing my job for me. I just need some hints about how to begin with that.
  I'll be using Microsoft Visual Studio 2010 Ultimate.</p>
  
  <p>How can I use this webservice in winforms application?</p>
