Reference issue while compiling code inside a .net core 2.0 app.

[Magnus, Sweden]

Hello,

I'm really stuck on this issue, what reference should I add to make it work? I'm almost on the way to give up on porting to core.

It just claim that there is no console class. This was never a issue to figure out in .net framework 4.


Regards,
Magnus
