title: How to Add web service reference into class library project .NET 4.0
body: <p>I want to add web service refernece into .NET class library project 4.0.</p>
  
  <p>(previously web service was used into ASP.NET web application 2.0 as "add web service refernece").</p>
  
  <p>I can't find "Add web reference" but there is an option to add "Add service reference".</p>
  
  <p>Please suggest, both can be same or "Add service reference" is only for WCF service.</p>
  
  <p>How can i add my web service reference into this class library ?</p>
  
  <p>Thank You</p>
