Needing to use an SFTP client and looking to build it in a .NET Core 2.0 application.
I was wondering if SFTP is already part of .NET standard 2.0 or will I need to use a 3rd party library for this, e.g. SSH.NET?
There's no SFTP client in any current (nor past) version of .NET.
See also SFTP Libraries for .NET and many others.
