Adding a Web Service Reference

I can add a web service reference in visual studio and use it. The Visual studio project builds without erros but when i try to run the unity project from the unity editor, I get this error:

CS0246: The type or namespace name `Irrelevant’ could not be found. Are you missing a using directive or an assembly reference?

I have the using statements in my class.

using Irrelevant;
using Irrelevant.AccountWebReference;

Any ideas?

Having the reference properly set up in VS won’t let Unity use it. However, this wiki article might help you out getting the service set up.
