That is a good example of how to call c++ from C#, but it essentially does
what we are already doing with Qt#. We already have an intermediate C
library and we are looking for ways to reduce that to an absolute minimum
size. We also are working on a new parser/generator called 'binge' that will
automatically bind C++ API's to C# and the CLR. It is being created
specifically for Qt# and eventually KDE#, but we are designing it to produce
bindings for any C++ library with an easy extension. Marcus, has even come
up with a way to handle transparent overrides of C++ virtual methods from C#.
Of course, we are looking for any and all ideas on how to minimize the
overhead and C library size. If you are interested in more, please come by
and see us: IRC openprojects.net #qtsharp.
