You can actually do both - describe objects that are the same as they
would be when compiled natively with C++ (unmanaged objects) and .NET
(managed) objects. And you use C++ language syntax (albeit extended) to
do that,

It would depend on the boost library. C++/CLI in the current incarnation
(well, VS2013, don't know about 2014) does have some limitations, and
some C++11 standard libraries cannot be used. std::thread and friends
among them. I don't know whether that would extend to boost::thread.
Smart pointers shouldn't be a problem as long as they are used in the
code belonging to unmanaged objects.

So the only way to really tell is to try those you need.
