Local Data Storage for Windows Phone

Here will be a very brief recap, please go to the MSDN links that I listed in the Related topic section to get a completed understanding.

There are three ways an application can store data:

• Settings: Store data as key/value pairs by using the IsolatedStorageSettings class.
• Files and folders: Store files and folders by using the IsolatedStorageFile class.
• Relational data: Store relational data in a local database by using LINQ to SQL.

For a Windows Phone application, all I/O operations are restricted to isolated storage and do not have direct access to the underlying operating system file system or to the isolated storage of other applications.

The TaskbarItemInfo class provides a managed wrapper for Windows 7 taskbar functionality. If you want to know more information about the Windows shell and native taskbar APIs, see Taskbar Extensions.
