Run my third-party DLL file with PowerShell

August 31, 2023 by Tarik

Yes, you can: Add-Type -Path $customDll $a = new-object custom.type You call a static method like so: [custom.type]::method() Instead of Add-Type, you can also use reflection: [Reflection.Assembly]::LoadFile($customDll) (Note that even the above is calling the Reflection library and the LoadFile static method.)

Enter-PSSession is not working in my Powershell script

June 13, 2023 by Tarik

Not sure if it is a timing issue. I suspect it’s more like Enter-PSSession is invoking something like a nested prompt and your subsequent commands are not executing within it. Anyway, I believe Enter/Exit-PSSession is meant for interactive use – not scripting use. For scripts use New-PSSession and pass that session instance into Invoke-Command e.g.: … Read more
