I'm just wondering - the last release of Sandcastle is from May 2008, and it's still listed as Pre-Release Software/CTP and it's not even licensed anymore, as the EULA specifially says:
2.TERM. The term of this agreement is until September 1, 2007, or commercial release of the software, whichever is first.
As Sandcastle is rather "heavy" anyway, I just wonder if it is still the right thing to use, or if there are alternatives to create XmlDoc Documentation? (Alternatives = something I can run from my build to generate at least HTML, preferably PDF as well).
Nobody mentioned Docu, a recent project initiated by James Gregory, dev lead on FluentNHibernate.
It's a very simple and easy to use tool that generates html documentation a la rdoc. You can easily modify templates since Docu uses Spark as the view engine.
Here is the FluentNHibernate documentation built with Docu.
