Hi Peter
When you say "No output" do you mean no files are generated? The reason I ask is that you're talking about intellisense which implies that you have something.
If no files are being generated I'd check the following -
If you're using Vista, make sure that either the output directory is one where elevated priveleges aren't needed (i.e. "My Documents" etc) or run MyGeneration with suitably elevated privs (right click - "Run As Administrator")
Going back to your intellisense question, assuming the class has been generated ok (and is not empty) then have you put the relevant "Imports"/"using" statement at the top of your class - dumb question I know but sometimes it's the easy stuff that gets forgotten.
Hope that helps
Martin
