Cerbuino Bee - 'System.NotSupportedException' occurred in Microsoft.SPOT.IO.dll

I got the FEZ Cerbuino Bee and update the firmware by following the instruction from: GHI Electronics – Where Hardware Meets Software

No problem.

Then I created a NETMF 4.2 console application in visual studio 2010 and wrote a very simple program (Debug.Print() ) for FEZ Cerbuino Bee.

Compile was fine, but when I tried to deploy the application. The debugger shows: “A first chance exception of type ‘System.NotSupportedException’ occurred in Microsoft.SPOT.IO.dll”.

It still gave me the expected result. I wrote couple different test programs. It seems the board works as the program instructed, but everytime the above exception shows up, which makes me have some concerns…

Anyone can give me a hint about how to resolve it? I have been using EMX for quite a while and haven’t came across any exception like thie before.

Your help will be highly appreciated :slight_smile:

You can safely ignore that exception
