Return Value

The isolated storage file that corresponds to the isolated storage scope based on the calling code's application identity.

Isolated storage is disabled.


This method is typically used with the IsolatedStorageSettings class to provide settings that are available to all applications in the domain.

An application on a virtual host domain (Web site) shares a group quota with all the other applications in that domain. This enables multiple applications in the same domain to share a single quota. Note that domain in this context refers to a virtual host domain, such as, not to an application domain.

The default isolated storage size for a group quota is 1 megabyte. To increase that quota, use the IncreaseQuotaTo method.

To obtain the isolated storage for a user for the current application in the domain, use the GetUserStoreForApplication method.
