I am writing an application (windows servcie) that processes files once they are created. I didn't know if I should use a timer or a filesystemwatcher. I googled the difference, and a small sampling of people said they found filesystemwatcher to be unreliable. Do you agree? I remember writing an application with the FSW about five years ago and I don't recall any issues. And I think it would have been improved in VS2010. So thanks for any opinions on this.
