Remarks
In ASP.NET, the IFileChangeNotificationSystem interface provides access to internal file-change notification management.
The IFileChangeNotificationSystem interface is used internally by the HostFileChangeMonitor class.
When a cache implementation runs in an ASP.NET application domain, ASP.NET implements an IFileChangeNotificationSystem interface through the Host property. The HostFileChangeMonitor class detects this property and uses the ASP.NET file-change notification system to evict cache entries based on file-change notification.
In non-ASP.NET applications, there is no host environment that implements a custom IFileChangeNotificationSystem interface. As a result, the HostFileChangeMonitor class uses the FileSystemWatcher class of the CLR.
Methods
StartMonitoring(String, OnChangedCallback, Object, DateTimeOffset, Int64) |
Registers a file path to monitor with the host environment. |
StopMonitoring(String, Object) |
