Jim,
There is a fourth copy under App.
Are these projects within a single solution, or did you use multiple
solutions?
If you use 3 solutions (Level2, Level1, App), then if you change Level2 you
need
to recompile Level1 also, before recompiling App.
But : we use different solutions (each having multiple projects) and
sometimes
we encounter problems (sometimes version problems like you saw, usually
problems with the xml-documentation files) that go away when you:
- close (all) VS
- empty all bin-directories
- start VS
- open each solution and rebuild
