Here is a good explanation for this warning.

You need to provide explicit access controls for your file.

Try the following code:

using (var fs = new FileStream(@"g:\temp_test.txt", FileMode.Append))
{
   fs.SetAccessControl(new FileSecurity(@"g:\temp_test.txt", AccessControlSections.Access));
   using (var s = new StreamWriter(fs))
   {
      s.WriteLine("Test");
   }
}
