Over the years, one of the great dilemmas facing software developers and big business is how to make the data available to those both inside and outside, without sacrificing security and make it efficient. When it was assumed that the information being shared was to create tapes and disks, email, and then import the data. Another problem for software developers are giving users powerful features without having to spend hundreds of hours trying to give users want they want. Web Services, also called XML Web Services provides developers with these skills and more.
In addition, exposure data can also provide developers and perform remote actions by creating a Web service that people can use elsewhere. An example is a web service connected to a webcam in the ballpark of the Seattle Mariners (called Safeco Field) that lets me see the ball game on my computer in my office.
One of the really great features of Web services is that you can create with them. NET and C # if you have the full version of Visual Studio. NET.
Web services provide solutions to tasks that either do not make sense for you to create or maintain the code, or for which it should have access to the data available outside of another company or facility. A couple of examples of the use of Web services are receiving contributions from the stock market or weather information service anywhere in the world. These examples are used in this chapter to discuss what Web services are and how you can use in their applications.
When talking about the issues that I mentioned in this chapter:
- Provides an overview of Web services and how you can use in C # Express.
- Explain what web services are available and how to find them.
- Shows how to create references in their application to the desired Web services.
- Shows how to use Web services in their own applications, with examples of the addition of stock quotes and weather information for Web services.
