public class NosDBDependency : CacheDependency, IDisposable, IBinaryProtocolSerializable
Remarks

You can add items with dependencies to your application's cache with the specific overloads of Add and Insert methods.

When you add an item object with NosDBDependency to cache, it monitors a specific database. Any changes in the database will remove items associated with it from the cache. This helps you avoid losing changes made to the object between the time it is created and the time it is inserted into the cache.
