When Visual Studio deploys the assembly to the Netduino is it sending the MSIL or has it used NGen to create native code that the board can understand? If it doesn't use NGen, could it or does that not make sense for these sorts of projects?
I'm wondering how it all actually works

VS deploys IL to the Netduino. This is then interrpetted (not JIT'd) by the framework.When Visual Studio deploys the assembly to the Netduino is it sending the MSIL or has it used NGen to create native code that the board can understand?

Not sure if you'll find this project interesting but Corey has been working on SimpleNGEN.

While certainly not impossible, Ngen (or really, just a native compiler since you would do this at compile time on the host, not the target) would require a separate compiler for each MPU architecture that NETMF has been ported to. NETMF itself is relatively easy to port to new processor families and architectures, but creating (or licensing) a native compiler for that processor is not.
There are other possible approaches, but I just wanted to make it clear that providing a single ngen-like compiler is not as simple as it sounds. Ngen itself is simply a compiler (well, more than one, as there are a few flavors) which uses information about the runtime environment it is installed in to optimize and compile .NET assemblies to native code.
