when you adding web reference you should give a name to it by using this name in your code you can access to the service and consuming service functions as well

When you add web references, Visual Studio automatically generates strongly-typed proxy classes for you, base on the definition of the web service. In other words, after adding a web reference, you can straight-away use the generated proxy classes to communicate with the web service.

Below is an excerpt from Creating and using Web Services with the .NET framework and Visual Studio.Net that explains in details what a web reference is:

Visual Studio.Net Web References are proxy classes created on the client to connect to the Web Service running on the server. Inside of the IDE Web references automatically generate code and insert hidden files into your project. This is required because .Net is type safe and in order to compile code that uses the Web Service, the client has to know the method signature of each method that is called.

This is nice as it provides full IntelliSense support in the development environment. However it also means that you need to refresh the Web Reference whenever the Web Service interface changes.

The generated proxy class code is stored in the \WebReferences folder beneath the application directory. There is one source file class for each Web Reference you create by the name of the class you publish. Although you can look at the source you shouldn’t change this code as it will be overwritten next time you update the Web Reference.

To use a Web Reference simply add the namespace of the Web Reference. By default it’ll be YourClientNameSpace.ServerClassNameSpace. Make sure you add this namespace to your list of namespaces (using … in C# or imports … in VB).
