Last two days, we discussed about Windows Phone 7 Page State. We learnt about saving and retrieving state of a page whenever require. Page State defines the current visual state of application page. Page state is accessible within that page. But think about a condition where you want to save values to the state and want to access them across the application. Then what to do? You have the option to use the Application State in that case. Application State stores data values which can be accessible by multiple pages. In this tutorial chapter, we will learn about Application State and in the next chapter, we will see an actual implementation of the same with a small demo. Read to know more about Application State.
