Just took the survey and asked for more sample code, as in, how/when/should I use this class/method/property. The docs could also have more wiki style links. I like to see things like "what points here", "recent changes", and wiki style template boxes for better navigation.
It would be cool to have a language translator, that could go from msil, c#, vb.net, f#. something like what is built into Reflector.
