We have been using the .NET SFTP.NET client for over 10 years. However, we are having trouble connecting to a new client's server that seems to be using diffie-hellman group exchange sha256:

Exception: (Buffer error: start>end)
RemoteIdentification: SSH-2.0-OpenSSH_4.7
SFTP.NET version: still fails with latest 3.4.9.128

We are able to connect using Core FTP app with this handshake:

SH-2.0-OpenSSH_4.7
