One of the most interesting and talked-about features of the Microsoft .NET Framework is the ability to quickly and easily create Web services. A Web service enables developers to access remote methods and data using open standard protocols for transport and packaging. Web services use port 80 (the standard HTTP port) and XML to send and package data respectively.
By utilizing Web services, you can transmit data from any given host on the Internet to any other given host because Web services use TCP/IP to transport data. This enables you to build truly distributed applications without having to worry much about making sure the two hosts can communicate successfully. Best of all, Web services are easy to create and consume . If you can build a Web form, you can build a Web service.
