PhysicalFileProvider.UsePollingFileWatcher Property


Gets or sets a value that determines if this instance of PhysicalFileProvider uses polling to determine file changes.

By default, PhysicalFileProvider uses FileSystemWatcher to listen to file change events for Watch(String). FileSystemWatcher is ineffective in some scenarios such as mounted drives. Polling is required to effectively watch for file changes.
