Great, thanks! Any reason you are using FluentFTP and not the CLR's classes ? We would like to keep this library without dependencies

See https://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.aspx

Ohh, you're right, I've been thinking about it, but just for time economy decided to use FluentFTP. I will rewrite it to CLR :)

Ok, moved from FluentFTP to CLR

Thanks, looks good! Any chance you can add tests for this new Source class?

Yep, I'll do it in this week

Hm, but how can I test ftp source?
I found only approach like this: https://dougrathbone.com/blog/2012/09/26/integration-testing-ftp-connections-in-net
Is it acceptable way to do it?
