@MattHodge Thanks. I‘ll try that. I should have known that I find a solution in your repo 👍

Just trying to run run-ngen.ps1, but Packer suddenly stopped the virtual machine

...
    vmware-iso: 2>    Compiling assembly System.Management.Automation, Version=3.0.0.0, Culture=Neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=msil (CLR v4.0.30319) ...

    vmware-iso: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
==> vmware-iso: Stopping virtual machine...
==> vmware-iso: Deleting output directory...
Build 'vmware-iso' errored: Script exited with non-zero exit status: 4294967295. Allowed exit codes are: [0]

==> Some builds didn't complete successfully and had errors:
--> vmware-iso: Script exited with non-zero exit status: 4294967295. Allowed exit codes are: [0]

==> Builds finished but no artifacts were created.

And now I remember. I had this problem with scripts/compile-dotnet-assemblies.bat as well and removed the step in #58

So it's time to investigate what's the real problem here...
