Should I use Resource Pools to add a VHDX-file to my HyperV VM?

Hi,

I am trying to figure out how to add a .vhdx file to an existing VM. It seems like this can be done with the ResourcePools example, but I have not succeeded.

Here is an example:
My VM folder - c:\program files\myvm
My Vhdx file - c:\program files\myvm\Virtual Hard Disks

Should I then write:
ResourcePoolSamples.exe CreatePool VHD "myvmPoolId" "myvmPoolName" [p]c:\program files\myvm[p] [p][h]c:\program files\myvm\Virtual Hard Disks[h][p]

(I have tried to write the arguments directly in the program.cs, and that helped a bit). But still, before I continue to change a lot more, it would be nice to know if I am in the right direction. I am really guessing a lot...

I found a solution using some code from https://github.com/jscarle/HyperV.NET, at least it worked for setting the number of processors, and I think it will be similar with the VHDX files.

Start with the ResourcePools example and its Program.cs entry point, then compare the reported CreatePool VHD invocation with how the sample parses its arguments. Done means establishing whether the VHDX path and pool parameters are supported and documenting the correct usage or identifying the missing sample guidance.
