Answer 1

I have encountered a similar issue. The problem is that FtpWebRequest (incorrectly) prepends '/' to rename requests, as can be seen from this log (upload & rename):

URL: 
  http://127.0.0.1/Test.txt
FTP log:
  STOR Test.txt.part
  RNFR /Test.txt.part
  RNTO /Test.txt

Please note that this problem occurs only when you are uploading to the root directory. If you changed the URL to http://127.0.0.1/path/Test.txt, then everything would work fine.

My solution to this problem is to use %2E (dot) as the path:

URL:
  http://127.0.0.1/%2E/Test.txt
FTP log:
 STOR ./Test.txt.part
 RNFR ./Test.txt.part
 RNTO ./Test.txt

You have to url-encode the dot, otherwise FtpWebRequest would simplify the path "/./" to "/".
