    Part 5 is a continuation of the adding a Push mode to our Stock Quote application as we now look at the Phone side.We setup the notifications by calling DoConnect in a class called SetupPush that was mostly lifted out of  the WP7 Labs example...

    Now we have shown the development of the UX for the quoting application however the real value in this is the setting of alerts that specifies when the user wants to be notified of a change in the value of a stock. Microsoft Push Notification (MPN) is used to setup a push notification. Thus Silverlight is only one part of the development of a robust phone application as we must also be proficient in writing .Net services. Some argue that most phone applications will be Cloud application but I think that is little naive as there will always be some suited to phone only code such as a game.

    Part 2 showed how we built our UX for our Stock quoting application now we will add the data access that I want to hide behind an interface so that I can change providers easily. This must be accomplished without using MEF as sadly MEF is not available for the phone as Reflection.Emit was omitted from the CLR for the Phone. Another design goal is have this data access occur on a background thread as we must issue WebClient calls to obtain the real data for the Quote objects. The Background thread will use MVVMLight’s Messaging to communicate between the threads, I could have just as easily used native events .

    In Part 1 we started the development of our Stock Quote application and used MVVM Light to add a command handler for the Add button that the user will use to add symbols to monitor. Now we continue the process by changing the ListView so each row will look like:

    When the user touches the + button then a grey rectangle with the Volume, Ask etc is displayed with additional quote information.

    This is the first of series of articles describing the development of a Stock quoting and Alerting application for the Windows 7 Phone. I want to make it clear that this is strictly a demonstration application to show off the capabilities of the phone and the rich development environment  that it provides. One of the key points is having Silverlight available to deliver a great look and feel that has become standard on IPhone apps. Silverlight is especially good as it lets your developers and graphic designers work in concert using Visual Studio and Expression Blend for the Phone.
