Have you tried entering the path/GUID to the container’s base layer? If you’re using Docker’s windowsfilter dir struct, itll be the directory directly under the windowsfilter folder that has a layer.json with a ”null” entry. It’s easiest to find the base layer in a freshly installed docker environment.

I just tried the above, using:
ls -depth 5 -filter layerchain.json | ? Length -eq 4 | select -Property length,Directory
I found that there are only two base layers that have null as content in layerchain.json (note not layer.json, because that does not appear to exist in the current version of Docker).

Using either directory as environment variable in the unit tests gives me the following output:
System.AggregateException : One or more errors occurred. (HCS function call returned error.) ---- Microsoft.Windows.ComputeVirtualization.HcsException : HCS function call returned error. -------- System.Runtime.InteropServices.COMException : The container operating system does not match the host operating system. (Exception from HRESULT: 0xC0370101)

Note that I'm running on Windows 10, so perhaps this library only works with native Windows Server containers? I can run nanoserver/iis using docker though, so I'll see if I can dive in their source code to see what happens on hcsshim level.

Edit: Also I had to run Visual Studio as administrator, else I would get an AccessDenied error.
