WebServices in VS 2005 Whidbey

Question

Hello, I'm working on a web service with Visual Studio 2005 'Whidbey' an I'm relatively new to web services. I don't know how to execute the service from a website as It seems that only works executing from VisualStudio. No bin directories are created with the application, only when I choose to 'Publish Website' but doesn't work either. Always getting the error: Could not create type 'Login'Line 1: <%@ WebService Language="C#" CodeBehind="Service.cs" Class="Login"%> Please help!
