Understanding Moonlight; Is it a framework?

I'm trying to understand if moonlight is a framework which is similar yet independent to the mono framework in exactly the same way as silverlight is similar yet independent for dot net framework.

I'm 开发者_开发百科trying to write a library that works for both moonlight and mono and I was wondering if I would need to target specific frameworks (as is the case with silverlight and dot net).

Moonlight uses the Mono runtime but, like Silverlight, uses a subset of the available .NET framework. So yes, you'll need to target different frameworks for desktop vs Moonlight (Moonlight uses the 2.1 profile, same as Silverlight).
