Maverick .NET is an SSH API for the .NET platform written in C#. The project was originally a commercial API that was mothballed in 2009 due to resource constraints.
We have now revived the project and released the SSH2 implementation under the GPLv3 license for open source developers.
DotNetSSH is a pure .NET implementation of the SSH2 client protocol suite. DotNetSSH development is alive and active. DotNetSSH is a fork of Tamir's excellent SharpSSH, itself is a port of JCraft's java Jsch.
