What is i understand is slight variation. C# code -> compiles to MSIL -> JIT Compiler -> Managed native code -> loaded into CLR -> Executes Managed Native On demand of code. This means an additional layer(CLR) of code optimization. All objects/modules are not executed by CLR, only code needed by the program/User is executed and they say...this means less overhead and code will execute even faster than a traditional C++ program. >The other important difference - as I understand > it - is that MSIL is compiled on demand before execution whereas Java > ByteCode can be interpreted or compiled, in other words, the difference is > in how aggressive the Java JIT compiler is (does it compile everything or > only 'critical' / oft-used pieces?). "Java ByteCode can be interpreted *or* compiled" Are you talking about eg(IBM's version) Java Compiler, where you can complie Java code straight to native code(just like C++) and NO interpretation. I might be wrong but from what i understand Bytecode is *always* interpreted by JIT Compiler before it is executed.
