I've been trying this VS2005 add-in for the last couple of days, and it's safe to say that it
ROCKS!
From the site:
GhostDoc is a free add-in for Visual Studio that automatically generates XML
documentation comments. Either by using existing documentation inherited
from base classes or implemented interfaces, or by deducing comments from
name and type of e.g. methods, properties or parameters.
In use, it's great for going back over hurriedly written code to write the in-code comments we're all SUPPOSED to write as we go - took me about a minute to completely document a complex ASP.Net server control, and I had to adjust the comments of only 3 methods.

Roland Weigelt's GhostDoc - you know it makes sense!
