• We now look at how we can provide a .NET program that accesses a Web Service.
• Note: elsewhere, accessing a Web Service is called consuming a Web Service.
• Suppose a program running on an external site wants to call the ToFahrenheit method provided by the Web Service that was given earlier.
• What we can do is to get the code of the program to generate an HTTP request, ...
• ... send it to the webserver providing the Web Service, ...
• ... and then decode the reply that gets sent back.
• Once again, there are tools in the .NET Framework that help us to do this.
