Microsoft releases (CTP) an NDoc replacement
With the news that the main NDoc developer has stopped support for the community project it looked like the ability to compile source comments into help files was grim for .Net 2.0. Microsoft has stepped up with a new product to replace NDoc - Sandcastle. It looks like they have released a version of Sandcastle for download. Note that this is a Community Tech Preview (CTP) and therefore may not be fully functional.
I’ve not tried it out yet, but do plan to.
