WP7 Isolated Storage (1)-Introduction to Isolated Storage

What is Isolated Storage?

Isolated Storage is also called an Isolated Storage space. It is used to store data locally on Windows Phone 7. Is a folder structure for storing applications:

Isolated Storage is used to create and maintain local Storage. The architecture of WP7 is similar to that of Silverlight in Windows. All read/write operations are restricted to the file system that isolates the storage space and cannot directly access the operating system of the magnetic layer. This prevents unauthorized access and destruction of other applications, and enhances security.

Tip: if you have two applications that want to share the same data, you cannot use local storage. You can use web services.

Tip: there is no limit on the quota of isolated buckets in WP7. The application should only save the necessary data. When Windows Phone has only 10% of the available space, the user will receive a reminder and may stop the current application. This is a poor user experience for users.

You can perform directory operations, file operations, and application configuration information in an isolated bucket.
