title: FileNotFoundException on file that exists - C#
body: <p><strong>Hi</strong></p>
  
  <p>I am trying to read a plain text file named "test.txt" from my system but all the attempts
  File.Exists(), StreamReder are not getting the file, that is not a new task for me but i am irritated due to this strange behavior. I have given full permissions to the file but in vain. I am doing the test in a C# console application. The system has a fresh installation and I am wondering of any permission issue when run in debug mode. I also copied the file to Debug folder but still same error. Can anyone please guide me about this? Thanks in advance</p>
