2.0.0 preview Module loading error (pb loading netstandard, Version=2.0.0.0)

Description

When trying to launch the PowerShell preview 2.0.0 in VSCode, I've got an error that I was able to pin down to the importation of the PowerShellEditorServices module. When trying to load the module by itself, there is three Add-Type errors. When trying those Add-Type manually, I've got the same errors that say Unable to load one or more of the requested types. I checked the LoaderException objects, and it seems to boil down to that message:

{System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

Files attached

EditorServices-reportlogs.zip contains:

• vscode-powershell.log
• Start-EditorServices-EditorServices.log (log level: diagnostic)
• Import-Module.log (manual module importation, verbose)
• LoaderException.txt (random loader exception among loads of identical ones)

@XPlantefeve what version of the .NET Framework do you have installed on your machine?

It's 4.7.02046 apparently. Taken from my registry:

I believe only .Net 4.7.2 includes netstandard.dll, so PSES will need to distribute that assembly and conditionally require it if it's Windows PowerShell
