Thanks everyone for your comments.

I actually found one of the bit flags in the Attributes property (ReparsePoint) of DirectoryInfo objects seems to work to detect directory symlinks.

Since Windows doesn't have any notion of a symlink, it's not likely
that there will be any such mechanism in the MS runtime. 

Actually, there are symlinks on NTFS:

But they are not popular :)
Linux/Unix systems though, you can just use Mono.Posix to make this
determination.  I believe Mono.Posix is released as MIT/X11 so you
could distribute it with your app and its methods will probably just
throw exceptions on Windows.
