Powershell Script started with SshCommand keeps running even after connectivity loss

I wanted to start a specific .ps1 file with SSH, so I tried running the script with both SSH.NET and SSH on the Terminal. After testing a little bit I noticed, that after a connectivity loss the Script started with the Terminal drops itself regardless of the progress, on the other Hand with SSH.NET the .ps1 file keeps running even if the connection is dropped.

for SSH.NET I used this Code to start the .ps1-File:

sshc.Connect();
using (var cmd = sshc.CreateCommand("powershell.exe -command C:\\Test.ps1\""))
{
    cmd.Execute();   
}
sshc.Disconnect();

So I want to know why does SSH.NET keeps the script alive and is this a wanted feature

Commencez par le flux SSH.NET présenté en utilisant Connect(), CreateCommand(), Execute() et Disconnect(), puis reproduisez le comportement en interrompant la connectivité pendant C:\Test.ps1. Comparez-le au comportement du terminal et déterminez si l’exécution de la commande est censée continuer après la perte de la connexion SSH ; documentez ou testez le comportement qui en résulte.
