Hi Gurus,
Is there a conflict issue with GHI.Premium.Hardware and any other assemblies?
I get an exception when debugging just having GHI.Premium.Hardware referenced along with the following;
Gadgeteer
GHI.Hardware.FEZCerb
GHI.OSHW.Hardware
Microsoft.SPOT.Graphics
Microsoft.SPOT.Hardware
Microsoft.SPOT.IO
Microsoft.SPOT.Native
mscorlib
System.IO
Apologies in advance if it’s really obvious. I’m new at NETMF! 
1st of all welcome!
Looks like you’re using either a Cerb40, CerbuinoBee, CerbBot or Cerberus board.
The Premium library only works with specific boards. It’s part of the Value Added aspect of their hardware.
This GHI page shows which boards are which: https://www.ghielectronics.com/catalog/netmf-offer-types
Aha! A simple as that.
Yes, I’m using a CerbuinoBee. TBH I’d assumed that any libs unavailable to that hardware, I wouldn’t of actually been able to reference at all.
Thanks for the kind welcomes and super fast replies. 
Apologies that I can’t tag both replies as the correct answer, so just chose the first.
Done!
