SFTP Server Lite is an experimental .NET SFTP server library that is extremely simple to use.
It can be used to easily add SFTP server capabilities to your .NET application, no matter whether you use C#, VB.NET or any other .NET language.
Check out the sample code to see how it works and what it can do! If you have any questions, just ask me:

This project has been acquired by Rebex and a greatly improved version is now available as Rebex File Server component for .NET, .NET CF, Xamarin.iOS and Xamarin.Android.
