SFTP library for .NET?

I currently use WinSCP. It has a .NET assembly that can be used to programmatically create and manage SFTP, SCP, FTP, and WebDAV connections.

Here's an example from their documentation:

using System;
using WinSCP;

class Example
{
    public static int Main()
    {
        try
        {
            // Setup session options
            SessionOptions sessionOptions = new SessionOptions
            {
                Protocol = Protocol.Sftp,
                HostName = "example.com",
                UserName = "user",
                Password = "mypassword",
                SshHostKeyFingerprint = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
            };

            using (Session session = new Session())
            {
                // Connect
                session.Open(sessionOptions);

                // Upload files
                TransferOptions transferOptions = new TransferOptions();
                transferOptions.TransferMode = TransferMode.Binary;

                TransferOperationResult transferResult;
                transferResult = session.PutFiles(@"d:\toupload\*", "/home/user/", false, transferOptions);

                // Throw on any error
                transferResult.Check();

                // Print results
                foreach (TransferEventArgs transfer in transferResult.Transfers)
                {
                    Console.WriteLine("Upload of {0} succeeded", transfer.FileName);
                }
            }

            return 0;
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: {0}", e);
            return 1;
        }
    }
}

Does .NET Core 2.0 have SFTP client?

There's no SFTP client in any current (nor past) version of .NET.

See also SFTP Libraries for .NET and many others.

SFTP with .NET 3.5

There are commercial solutions:

• http://www.rebex.net/sftp.net/
• http://www.enterprisedt.com/products/edtftpnetpro/overview.html

...and free:

• http://www.tamirgal.com/blog/page/SharpSSH.aspx
  

I personally have no experience with any of them.
