Re: [Boost-users] Support for VS 2005 C++/CLI offtopic: why C++/CLI?

just a beginners question, not want to start any flames:
why are you using C++/CLI mode, if you are using portable libraries like
boost anyway? why not build a native C++ application? what are pro's and
con's? i must admit that i never got my head up into .net stuff, because
i thought: "no way, i completely will loose cross platform." but now
with mono, thats not true that much anymore. i heard that bytecode might
be even faster than native code, because these bytecode JIT compilers
can "magically" optimise speed at runtime!! ( see
http://psyco.sourceforge.net/, http://www.kano.net/javabench/ ,
