Hi,

I want to create a service in .NET to transfer files between SFTP servers.

What will be the best way to choose as I know WCF doesn't support SFTP, does SFTP is supported by .NET Core.

Thanks & Regards

Can you clarify that all you want to do is download files via SFTP from Server A and upload those same files to Server B. Your question is phrased as though you want to create your own FTP server which, gonna be honest, is pointless.

Hi David,

I am rephrasing my requirement -
I have two SFTP servers as inbox and outbox. File will come from external application to SFTP-Inbox and I need to transfer the files through a service and using parallel programming. I will expose 4 different service who will continuously process the incoming files parallel. I mean services will not wait for one file process to be completed. What is the best way to perform the task. Does through WCF I can perform the task. And does .NET core supports SFTP endpoints?

Nothing supports SFTP, or any other variant of FTP, as a service endpoint. The FTP family of protocols are designed for transferring files from one computer to another, not for invoking services.

If you want to process the files in real-time, you'll need to install a service on the source server, using something like the FileSystemWatcher component to monitor the source folder for new files. You'll then need a library like FluentFTP[^] to connect to the destination server and transfer the files over SFTP.
