Immediately delete image file after it being closed

In my program i have byte[] imgSource. I create image file in temp folder:

c#
  if (container != null)
  {
      string tempFileName = Path.Combine(Path.GetTempPath(), $"tempImage_{Guid.NewGuid()}_{DateTime.Now.Ticks}.png");

      using (FileStream fs = new FileStream(tempFileName, FileMode.Create, FileAccess.Write, FileShare.None))
      {
          fs.Write(container, 0, container.Length);
      }

c#
  if (container != null)
  {
      string tempFileName = Path.Combine(Path.GetTempPath(), $"tempImage_{Guid.NewGuid()}_{DateTime.Now.Ticks}.png");

      using (FileStream fs = new FileStream(tempFileName, FileMode.Create, FileAccess.Write, FileShare.None))
      {
          fs.Write(container, 0, container.Length);
      }

Then idk how, but it need to be opened, and delete itself after being closed, i coded this, but it doesn't work:

c#
    Thread thread = new Thread(() =>
    {
        Process process = new Process();
        process.StartInfo.FileName = tempFileName;
        process.StartInfo.UseShellExecute = true;
        process.EnableRaisingEvents = true;
        process.Exited += (s, args) =>
        {
            try
            {
                File.Delete(tempFileName);
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Failed to delete temp file: {ex.Message}");
            }
        };
        process.Start();
    });
    thread.Start();
}

c#
    Thread thread = new Thread(() =>
    {
        Process process = new Process();
        process.StartInfo.FileName = tempFileName;
        process.StartInfo.UseShellExecute = true;
        process.EnableRaisingEvents = true;
        process.Exited += (s, args) =>
        {
            try
            {
                File.Delete(tempFileName);
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Failed to delete temp file: {ex.Message}");
            }
        };
        process.Start();
    });
    thread.Start();
}

Idk why, but it delete itself immediately after being opened, or sometimes before it
