Describe the bug

The exception "Could not load file or assembly 'Microsoft.Extensions.ObjectPool....', Could not find or load a specific file (0x80121621)" is raised when I load (via Add-Type) and use a dll which itself uses Microsoft.Extensions.ObjectPool V7.

You should be using the package version that matches your framework version. E.g. net6.0 and 6.0.15. Does that combo work for you?

Package Version V 6.0.15:
