il-repack: Failed to load assembly when merging complete project

Hi all, I’m trying to merge a big set of the .NET Standard dll’s into a WPF project. Previously this worked fine but after upgrading some thing to the latest .NET Core / .NET Standard I seem to get the following exception:

The PowerShell file I’m using to build: https://github.com/devedse/DeveImageOptimizerWPF/blob/master/Scripts/GoRepack.ps1

The build failing on AppVeyor (it’s marked green but it’s actually failing): https://ci.appveyor.com/project/devedse/deveimageoptimizerwpf

I already tried changing the order and first passing netstandard.dll, but that didn’t help either.
