I don't believe so, unfortunately - at least, I don't believe there's
an officially recognised way of doing so. I expect there are ways you
*can* target 1.1, but I'd expect them to be as hacky as targetting 1.1
from VS.NET 2002. Personally, I think it's a bit of a crippling problem
with VS 2005 which I really, really hope gets fixed before it ships.
