Web Service

Learn how to build a web service using ASP.NET that calculates the area of a rectangle. Using VB.NET, you'll set up an ASMX file with a public function called `area` which takes the length and width as parameters and returns the computed area. The guide covers the entire process: from writing the Web Service, implementing and testing it, to calling the service from a client application. Discover how to manage XML results and utilize web references for seamless integration in your projects.
