PowerShell 6 - support for Windows GUI libraries

Question

I understand that the new PowerShell 6/core lacks support for Windows GUI libraries, I have developed some important projects in PS-5.1 using the Windows.Forms

Answer 1

One question I have is what you mean by "Upgrading" to PowerShell 6? On Windows there is no upgrade. You will run PowerShell 6 side-by-side with your existing version of PowerShell. So, if you want to keep running your old scripts that use GUI stuff, keep doing so in PowerShell 3, 4 or 5.1. If you want to start using PowerShell 6 in order to write scripts that will function on all platforms, then use PowerShell 6 for that. The good news is, you will continue to have both. (for now at least)
