Hi,

SSH.NET version 2024.0.0 works now on my solution on .Net Framework 4.6.2. I had to uninstall and install the package nuget SSH.NET after the upgrade from .Net Framework 4.6.1 to 4.6.2.
On Framework 4.6.1, removing the HostKeyAlgorithm does not solve the issue.

It seems the upgrade to .Net Framework 4.6.2 (or highter) is the solution.

Thank for your help.
Regards

Your application appears to be loading the .NET Standard 2.0 version of the library. That's probably expected when your application targets .NET Framework 4.6.1 but is unexpected if your application targets .NET Framework 4.6.2 because the library has an explicit target for that. How is the library being referenced?

This would probably stop that specific error but it's not a great workaround and there could be other problems:

connectionInfo.HostKeyAlgorithms.Remove("ecdsa-sha2-nistp256");
connectionInfo.HostKeyAlgorithms.Remove("ecdsa-sha2-nistp384");
connectionInfo.HostKeyAlgorithms.Remove("ecdsa-sha2-nistp521");
