Yes.  Mono provides an embedding API which allows an unmanaged
application to create and use managed objects:


This isn't terribly ideal, as it's a string-based API.  There is a
program called cilc which will take a managed class and generate a bunch
of C wrappers for each method exposed by the class.  This makes it easy
to use a managed class from C (and thus C++, if not perfectly from C++).

Let cilc handle the cumbersome unmanaged->managed invocation layer.
