Providing a WWW page for accessing the code

The methods of a Web Service are accessed through a webserver.
So we must also provide a WWW page that
- indicates that a Web Service is available
- gives the location of the file containing the code.
If you are using Visual Studio.NET's wizard, this is the second file that is automatically generated for you.
It will create the WWW page in a file with a .asmx extension.

For example, the file Service1.asmx could contain:

0068: <%@ WebService Language="c#" Codebehind="Service1.asmx.cs"
0069:                Class="ServerConvert.Service1" %>

As you can see, this WWW page does not contain HTML instructions.
Instead, it is just providing a directive to the webserver telling it that there is a Web Service, ...
... that it is in C# in the file Service1.asmx.cs, ...
... and that it is provided by the class ServerConvert.Service1.
