I've been struggling to get NDoc to work properly with Beta 2 code this afternoon. I followed the instructions on the NDoc wiki to get it to be able to open the .exe, but then couldn't seem to get much further for a while. After a few failed attempts I've set my Beta 2 project to publish XML documentation, rebuilt my solution and configured NDoc to look at that XML file through the SlashDoc setting. All is now working happily, and the output produced is very smart indeed.
