OK. I want WinSCP to prompt the user the first time it sees a new host key. I know how to do that from command-line, I just haven't been able to figure out how to do that directly from scripting/automation or .NET assembly. In particular it would be very convenient if this can be supported from .NET assembly. For now, I'm invoking a WinSCP command-line shell under a new Process, but using .NET assembly would be much nicer. Thanks.

Hello, in using the new .NET assembly, is there a way to have it prompt the user (e.g. pop up a MessageBox) to accept the host key? Thanks.
