You are mixing terminology.This thread is not about managed code but rather about garbage collection.

Unmanaged code might very well utilize garbage collection through compiler or library support.

That leaves the advantage of providing selective garbage collection in languages supporting manual memory allocation, which can leverage software architecture and performance.

Your statement, as well as the general notion of this thread, that writing code in languages enforcing global garbage collection, is faster or cheaper, is false. Given the situation of enforced vs selective garbage collection, I might even argue to the contrary.

This might not be popular on this board, but for C++ on Windows with varying target applications there is only Visual Studio in some flavour. Preferably with the VI plugin. Nothing comes close...
