Tiny CLR Code, how to know for what board

When i go to TinyCLR Code section and see all the code people have kindly posted how does one know for what board it will work on ?

For example, when i go here :
http://code.tinyclr.com/project/459/mcp23008-i2c-port-expander/

How does one determine if it will for for the FEZ Cerberus Mainboard ?

All boards run NETMF so all code you see there will run on almost any board, especially if it uses core features like I2C.

Sure, as long as the code sample is written in native NETMF. But if it’s Gadgeteer code that’s another story… Can be confusing to those just getting started. It would be nice to have something to indicate whether it’s NETMF or Gadgeteer and with the coming 4.2 release it might be good to distinguish between C# & VB.

… and a flag for 4.1 or 4.2 while we fix breaking changes…
