You can even debug programs compiled by ObjectAda (7.2) in Visual Studio, 
to a certain extent. However, I cannot tell if ObjectAda C++ interfacing 
works, I never tried that.

To be honest, it is a big mistake to make a library with only C++ 
interface, because that exposes not only the constants, subprograms and 
their profiles defined in terms of simple types, but it also does virtual 
tables and internal layouts of the classes. That is too much coupling from 
the software design point of view. (The same would apply to Ada's tagged 
types, unfortunately.)
