A web-service is a web application component that enables communication between applications for integration purposes.

Web-services follow a client-server architecture. An application "offers" a web-service (server) and other applications "consume" the web-service (client).

They are implemented over HTTP using requests and responses.

The main types of web-services are:

• SOAP (Simple Object Access Protocol)
• REST (REpresentational State Transfer)

Now run the application that look like as follows.

Now in the above we see our method that we are created in the webservice.cs file, so click on that method and provide input values and click on the "invoke" link as in.

The output will be as follows
