Thank you, I'm not skilled enough to understand though.

You are on the correct path!
The better design approach is to declare your interfaces first.

1) Declare interfaces
2) Implement this interface in your classes (C# class).
3) Implemtent the webservices classes from the same interface
4) In the WS, authenticate and authorize access to the business logic
implemented in your "true" classes (step 2).

Why?
Well - first of all it forces you to take a contract-first approach. Next it
allows you to call the logic from another "client" than the webservice that
exposes the methods. Second it de-couples the businss from the fact that it
is exposed as a webservices; not really a businnss entiity, is it?

Example:

public interfaces IOrder
{
string GetSomething(arguments...);
}

public class Order : IOrder
{
//..
}

[WebService]
public class OrderService : WebService, IOrder
{

[WebMethod]
public string GetSomething((arguments..)
{
//authorize
//if not allowed access - throw UnAuthorizedAccessException!

//instantiate businnss logic

//return data
}

}

Hi, sorry for a crosspost but that other news group was showing last post was a
week ago so I guess it dosen't see much use...

I'm about to start a solution and I'm curious about the approach of a webservices project.
Should the objects be represented in classes such as...

public class Orders (ie Orders.cs) within a project
and then have the service be in a class like OrdersService.asmx
public class OrdersService : System.Web.Services.WebService
and this class contain only [WebMethod] 's

I guess another another way to ask the same question is..
Would it be less desireable if a class inheriting System.Web.Services.WebService
contain methods that are not [Web Method]
