Base class for backing stores. Contains implementations of common policies and utilities usable by all backing stores.

Implementation of IBackingStore that stores its CacheItems into IsolatedStorage.

Represents a CacheItem as stored in Isolated Storage. This class is responsible for storing and restoring the item from the underlying file system store.

This class is used when no backing store is needed to support the caching storage policy. Its job is to provide an implementation of a backing store that does nothing, merely enabling the cache to provide a strictly in-memory cache.

Not intended for direct use. Provides symmetric encryption and decryption services to Isolated and Database backing stores. Allows this block to use Security.Cryptography without having a direct reference to that assembly.
