1. At authorization through a script - everything works
C:\Program Files\WinSCP>winscp.exe /console /script="C:\WinSCPscript\script1.txt" /log="C:\WinSCPscript\script1.log"
open sftp://ubuntu@ec2-52-32-183-91.us-west-2.compute.amazonaws.com:22/ -privatekey=C:\WinSCPscript\ludm2.ppk

2. At authorization through Assembly - doesn't work
sessionOptions.Protocol = Protocol_Sftp;
sessionOptions.HostName = "ec2-52-32-183-91.us-west-2.compute.amazonaws.com";
sessionOptions.UserName = "ubuntu";
sessionOptions.SshPrivateKeyPath = "C:\WinSCPscript\ludm2.ppk";
sessionOptions.SshHostKeyFingerprint = "ssh-rsa 2048 2b:3f:51:0b:27:6d:7c:76:a4:a7:0b:3c:f4:f5:a1:c6";

C:\WinSCPauto>cscript script2.wsf
Error: Disconnected: No supported authentication methods available (server sent: publickey)

3. The field SshPrivateKeyPassphrase when transforming a PrivateKey to puttygen left empty.

How it is correct to establish sessionOptions?

I guess the problem is, that you do not escape the backslashes in the path to the private key file:

sessionOptions.SshPrivateKeyPath = "C:\\WinSCPauto\\ludm2.ppk";

If this does not help, set session.SessionLogPath before calling session.Open.
