A few people pointed out that my sample for uploading a bunch of images to an FTP site using Whidbey broke with Whidbey Beta 2, so I fixed it. Basically, there were some semantic changes:
--the FtpMethods enumeration moved to WebRequestMethods.Ftp.*
--the FtpWebRequest.Binary property changed to FtpWebRequest.UseBinary
Now it works again!
