Cleanup Method
Starts a background cleanup operation to remove unused files from the cache.
Syntax
Remarks
This method starts a cleanup operation to remove unused files from the cache. Files used earlier than MaxAge hours ago will be removed (passing 0 for will cause all files to be removed).
The cleanup operation is performed asynchronously in a background thread, so this method returns immediately. To cancel a cleanup operation, use the CancelCleanup method.
.NET Standard Notes
To call this method in an asynchronous manner call CleanupAsync instead. When the method completes (or an error is encountered) the CleanupCompleted event will fire.
