WinSCP Console background process [Exit status 2]

I am using the WinSCPnet.dll for creating ssh connection in my current project.
When I try to start a linux command as a background process with an ampersand "&" after the command, I always get an error (Connection has been unexpectedly closed. Server sent command exit status 2.) and the connection closes.
After searching the internet and forums I still didn't find a solution.
The error can be reproduced when opening the Console in WinSCP and try "sleep 30 &" (just for example).
When trying the same in putty it works.

Does anyone have a solution or an alternative method for starting linux commands in the background using SSH?

Thanks in advance!

This is not possible in the limited WinSCP console terminal. Use "Open in PuTTY" command to open a full-featured PuTTY terminal from WinSCP.
