In VS2003, there is a feature known as “Build Comment Web Pages” that was designed to take XML doc comments from your code, and create web page documentation.
If you try to find it in VS2003, you won't have much luck, and I thought I'd explain why. We got a fair amount of customer feedback around the disadvantages of the current implementation, and that it wasn't really very useful.
We've therefore elected to pull it from Whidbey. We are exploring whether we can provide a feature that meets our customers needs in the future, but it didn't fit into the schedule.
