Could you tell us why you want to check the code?

When I start writing my app (mbloggy) I was using Interfaces as plugins
(xmlrpc plugins), then I started reading info about SOAP and I'm in =
with it, the fact that SOAP supports any encoding makes me happy :-).
What I was looking for is to do the same that "Plugins in Mono" (M.
Icaza) says :-).
However, I'd like to ask something else: I want EVERY plugin be =
like I want, yeah, when I compile the plugin (the .dll) I'd like to
check the methods and validate the plugin, if the plugin is ok, compile
it and add some Assembly Info (AssemblyInfo, right?), where should I
look?, NUnit I think is to check compiled applications but I want to
'check' my code BEFORE being a .dll.
