Push notification is a term that has been around a lot. Almost every SmartPhone manufactured has an option for enabling push notification. The word 'PUSH' is a contrast to 'PULL'. It means rather than pulling the content from the server or requesting from the server, the server pushes the content or sends the response as soon as an update is available. On mobiles, this technology is a great battery saver. In web technologies, it saves a lot of server request traffic. There are tons of articles available on the internet about implementing this technique, but I found MSDN the best. Therefore, I went ahead and made the MSDN tutorial even easier for beginners. Remember, this is beginners article, but the idea of implementing a real life application stays around this. You can recode it as best as you can.
Over here, we are going to see a Silverlight application requesting for stock prices of Yahoo! The server will start pushing the latest stock prices. The stock prices are random numbers. The application is based on some assumptions.
