I convert several files and this seems to work OK. However when we try to move those files from the output folder they seem to be locked. And these files remain locked until i kill my service and restart it. Am i doing something wrong?

Directory.CreateDirectory(job.InputPath);
Directory.CreateDirectory(job.InputPath + "\\backup\\");
Directory.CreateDirectory(job.OutputPath);

_validator.ValidateAndThrow(job);

foreach (var fileName in Directory.GetFiles(job.InputPath).Where(x => x.EndsWith(".xml", StringComparison.InvariantCultureIgnoreCase)))
{
	try
	{
		var originalFileInfo = new FileInfo(fileName);
		var backuppath = job.InputPath + "\\backup\\" + originalFileInfo.Name;
		var originalText = File.ReadAllText(originalFileInfo.FullName);
		File.WriteAllText(backuppath, originalText, new UTF8Encoding(false));

		var fileInfo = new FileInfo(backuppath);
		// Create a Processor instance.
		Processor processor = new();

		// Load the source document
		XdmNode input = processor.NewDocumentBuilder().Build(new Uri(fileInfo.FullName));

		// Create a transformer for the stylesheet
		Xslt30Transformer transformer = processor.NewXsltCompiler().Compile(new Uri(job.ConversionFile)).Load30();

		// Create a serializer
		Serializer serializer = processor.NewSerializer();
		string outfile = SetOutputFileName(job.OutputPath, fileInfo.Name, job.MaintainFileName, job.UseInFileOutputPath);
		serializer.OutputFile = outfile;
		serializer.SetOutputProperty(Serializer.INDENT, "yes");
		transformer.ApplyTemplates(input, serializer);

		originalFileInfo.Delete();

		_logger.LogInformation("Output written to {outfile}", outfile);
		output.Add(new JobResultDto
		{
			Success = true,
			JobId = job.Id,
			Message = $"Output written to {outfile}",
			ErrorMessage = null,
			Exception = null,
			TimeStamp = DateTime.Now,
		});
	}
	catch (Exception ex)
	{
		_logger.LogError(ex, "Exception");
		output.Add(new JobResultDto
		{
			Success = false,
			JobId = job.Id,
			Message = null,
			ErrorMessage = "Unhandled Exception",
			Exception = ex.ToString(),
			TimeStamp = DateTime.Now
		});
	}
}
