Reviews for this release

Generally works real well. Have had some issues of unusual disconnects while trying to retrieve files from SFTP server.

Worked great in my scenario, where I just had to upload files to SFTP server.

This is really a good job. I only use ssh command and sftp. It works well.

The concensus among the user community is that the first review was done by someone with a competing, probably for-pay, product to Renci.SshNet. The 'troll' never responded with any details, where they were having problems, or any details of their experience. In fact, they posted that questionable review, and nothing else ever again. I keep up with the Discussion group, and can tell you that there is nobody at all dissatisfied with the release. Taking someone else's abandoned code, and using it as a basis of a new, current version that is in continual development is an accomplishment the entire community appreciates. I need to talk to Cisco routers, and this software does the trick. I wanted something with source so I could extend it. As it is written in C#, it comes with source that compiles under VS2012 and I use it with my VB.NET projects without a single 'fail'. So impressed am I that I've written blog posts of my own on using it, as well as trying to answer any relatively simple questions other users have on the discussion groups. Few are softwares where users feel compelled to help others use it. That alone should convince you.

Well, it works (I've only been using SFTP) but throwing undocumented exceptions when the connection fails and then not being able to dispose of the SftpClient object is just not good enough.

Some basic SSH functionality contains a few serious defects that need to be addressed to make this library ready for distribution. Otherwise, some decently written code and has ample test cases to get just about anyone started. Would otherwise be a 4 or 5 star rating.

Can you provide more information on the defects you're talking about ? Thanks!
