Thread Safety

The common language runtime uses this class to control access to isolated storage.

Isolated storage creates a unique storage area for use by an application or component. It provides true isolation in that the identity of an application uniquely determines the root of a virtual file system that only that application can access. Thus, each application has its own file area inherently assigned to it. This file area is fully isolated from other applications, making it essentially private.

Note   The Assert method, inherited from CodeAccessPermission.Assert, does not have any effect on IsolatedStorageFilePermission. The Assert will be ignored.
