c# - Consume web service in asp.net app from a class library

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.

Any ideas why this is not working in the class library.

Double check your configuration file includes the correct information for the Web service.

Try changing the URL behavior to dynamic as well.

Also, as John stated, I'm assuming you're adding the service to the class library because you intend to use it from the library, as opposed to other areas of the Web application.

"the credentials don't seem to work, and the call fails"...can you give a small stack trace of the error?

Just to clarify, in my current project, we use WCF endpoints within a class library with bindings and credentials. The same can be done for a SOAP ASMX Web reference as you're attempting.
