import lib for script operator

Just based on that error it seems like it could just be a .NET version incompatibility...Max implements .NET 4.7/4.8 depending on your Max version, whereas it seems your package required 5.0 or higher.

Got it! Thanks so much for the help!.. After installing .NET4.8 it works if i use it inside another function..    
inside the SimulationStep it doesnt compile, still, thats not an issue at all.. 
this is very cool, it was totally worth the effort..
