Note
File deletions are subject to intermittent failures because files can be in use simultaneously by operating system features such as virus scanners and file indexers. This is especially true for recently created files. For these reasons, it is important to add code to the code block that handles the IsolatedStorageException to retry deleting the file or log a failure.
