ASP.NET.in.a.Nutshell.Second.Edition [Electronic resources] نسخه متنی

When creating a web service, you can inherit from this class to gain
access to the built-in ASP.NET objects Application
(the current System.Web.HttpApplicationState
collection), Server, Session,
User, and Context (which
provides access to the built-in Request and
Response objects). If you don't
need to access these objects (or if you choose to go through the
Context property) you don't need
to derive your web service from this class.

When creating a web service class, all web methods must be marked
with the WebMethodAttribute. To configure
additional activities, you should also add the
WebServiceAttribute to the class declaration.
