[Ironpython-users] Assembly references: file does not exist?

If the C# app is in the same directory as the assembly you're trying to load
from Python, it would automatically find dependent assemblies in that
directory. ipy.exe probably isn't in that directory, so the managed loader
(which is largely driven by the directory containing the launching
executable, though that is something of an oversimplification) wouldn't find

I'd forgotten fuslogvw.exe, but that's usually the penultimate thing I do
when troubleshooting loading problems.
