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.

Where are the sample icons?

First, Microsoft has provided a set of sample icons for you after you install the Windows Phone SDK (To download the Windows Phone SDK, see Installing the Windows Phone SDK.) And you can find the sample icons at one of the following locations:

• C:\Program Files\Microsoft SDKs\Windows Phone\v7.1\Icons\dark
• C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Icons\dark
