Whidbey FTP Support
There is some support for FTP in Whidbey beta 1, but it still failed my real world requirements.
Using both the FtpWebRequest / FtpWebResponse and WebClient classes failed to connect to an embedded system running an ftp server that Windows Explorer had no trouble connecting to.
I tried two third party FTP components for .NET (Mabry's FTP/NET and CSpot’s FTPComponent). Both components succeeded in connecting to the server when run as Visual Studio 2003 projects (using their own sample code). But both components failed (typically by hanging in the class constructors) when run after conversion to Visual Studio 2005 (Whidbey beta 1).
It seems that at the moment, there’s just enough FTP implementation in Whidbey to work with some FTP servers, but not all, and just enough changes to interfere with the existing crop of 3rd party components.
