A month ago I searched for some tools that will generate C# classes out for my SQL database/tables. So I don\'t have to write DAL classes manually and to save a lot of time.
SubSonic is irritatingly short on documentation (which is one reason I abandoned it). Scott Kuhl wrote a "Getting Started with SubSonic" document (just Google his name and SubSonic) but parts of it appeared to be out of date.
Here is Scott's blog - a place to start at least.
Here is the document's home page. I was curious as to whether the document is indeed out of date and I think it is: the web page has a last updated date in 2006.
Unfortunately, I know of no other documentation and I did look for it.
Update: See the link to documentation that Rob Conery provided in his answer.
