It was already there, but not the main version.

.NET Compact and Micro had ARM versions.

There is also an Arduino (AVR) that uses .NET Micro as their OS.

I just want to emphasize the fact that not only is the .NET Micro Framework something that exists, but that it has been available since 2009 and remains so, under the items of an arguably much more agreeable license: Apache 2.0

One thing: the Netduino devices are ARMv7-M (Cortex-M3 and Cortex-M4) devices, not AVR

[FlorianRappl]

Exactly :)! For the Arduino you are potentially referring to the Netduino, which allows you to write applications targeting the .NET Micro Framework.

Re: Netduino - I've got one of them, works really well with Visual Studio, i.e. hitting break points, stepping through code running on the board etc.
