the Host code and never in the native? That means scripting languages

Runnig at Native speed...Dream or reality ? Posted by main\(\){}; at 12/12/2004 8:09:17 AM I can't ignore the speed of .NET managed applications in manipulating

heavy operations, like long loops, graphics, load time and many other
