SFTP Libraries for .NET [closed]

I've searched around and found that this fork of SharpSSH and SSH.NET are the most up to date and best maintained libraries for SFTP (not to be confused with FTPS) communication in .NET. SSH.NET is a clean .NET 4.0 implementation of the SFTP protocol, and I've used it in a couple of solutions with flying colors and great success.

The original SharpSsh seems to be dead and most other solutions either require installation of Windows executables or a bucketload of cash (or worse; both).

We use WinSCP. Its free. Its not a lib, but has a well documented and full featured command line interface that you can use with Process.Start.

Update: with v.5.0, WinSCP has a .NET wrapper library to the scripting layer of WinSCP.
