Session.Dispose leaves sftp-server.exe ghost behind

I noticed that I could not manually remove a file just uploaded to a SFTP site by my PowerShell script using Session.PutFiles. This is because the file was locked by a sftp-server.exe process (started by New-WinSCPSession) hanging in the background, even though I could confirm that Session.Dispose was called once the file was uploaded.

Is there a way to properly terminate the sftp-server.exe process once the SFTP operations are completed?

I am using WinSCP-5.17.9-Automation and the WinSCP Powershell module 5.17.8.1.

Do you have the problem with WinSCP GUI? Please post session log file both from the code and the GUI. Show us your code for WinSCP .NET assembly (WinSCP PowerShell module is a 3rd party project).

The problem has been completely addressed by making the following change in the PowerShell code:
