title: Consume web service in asp.net app from a class library
body: <p>My team and I have a asp.net web forms application and are using several class libraries. In one of those libraries, we are trying to consume a web service. The web reference was added in the web app project and the appropriate references have been added. The app compiles. When attempting to consume said web service in the class library, the credentials don't seem to work, and the call fails. However, if we take the web service call out of the class library, and consume it within the web app, it works.</p>
  
  <p>Any ideas why this is not working in the class library.</p>
