The IpoptApplicationFactory is usually only needed for the C and Fortran 
interface wrappers, I think. Does some example that uses the C++ 
interface directly work?

It may be an issue with VS9 vs VS10. I heard that there are some 
incompatibilities:

The binaries you downloaded were created by VS9.

Under the above link, they also discuss a way to build Ipopt with the 
C/C++ compiler from VS10, but linking against precompiled Fortran libraries.
