    using System.IO;

        private static SafeFileHandle OpenForWrite(ITracer tracer, string fileName)
        {
            SafeFileHandle handle = CreateFile(fileName, FileAccess.Write, FileShare.None, IntPtr.Zero, FileMode.Create, FileAttributes.Normal, IntPtr.Zero);
            if (handle.IsInvalid)
            {
                // If we get a access denied, try reverting the acls to defaults inherited by parent
                if (Marshal.GetLastWin32Error() == AccessDeniedWin32Error)
                {
                    tracer.RelatedEvent(
                        EventLevel.Warning,
                        "FailedOpenForWrite",
                        new EventMetadata
