Due to lack of Add-Type, C# code needs to be included in a precompiled DLL.
On Nano Server, copy Cloudbase.PSUtils.dll in C:\Windows\System32\WindowsPowerShell\v1.0.
And then proceed as usual:
Import-Module <module.ps1>
The Cloudbase.PSUtils.dll assembly can be rebuilt using the provided build script:
.\build.ps1
The script needs a copy of Nano Server's CoreCLR and PowerShell assemblies, which can be obtained from a Nano instance:
C:\Windows\System32\WindowsPowerShell\v1.0
and from the CoreCLR location, e.g.:
C:\Windows\WinSxS\amd64_microsoft-onecore-coreclr-powershell-ext_31bf3856ad364e35_10.0.10514.0_none_3bd975248393ca54
