So I was looking through the mono documentation and just out of curiosity I looked at the supported platforms and I saw this 
Wii is a supported platform, it says that I need to have an official license to upload code, but I was wondering whether this is just for game development or for actual cross compatibility with the .net framework and being able to compile code for the wii. If anyone has any experience with programming for consoles your advice would be greatly valued.

I guess it follows the same principles with other devices like Wii. You need the Dev SDK kit which has the cross compiler, debugger, etc but I guess then Mono provides them all for you. Checkout the homebrew community. They know plenty of stuff about developing for Wii your own stuff. Go to wiibrew.org that can be good place to start.
Dolphin emulates the Wii also so perhaps you can check out that aswell.
If you would like to program for wii/gamecube, you should take a look at
http://devkitpro.org
I succesfully compiled some of the example projects an ran it on my gamecube a few days ago.
It compiles into a .DOL file, (at least, the gc example projects) which can be opened with the Dolphin Emulator as well.
