Yes, it has but it also has gains that the unmanaged code doesn't like
GC. I missunderstod the discussion because I that he was asking a
question about the possibilities not the overhead. He should not be
dubious because there is a common type system, and it runns C++ etc,
And regarding the MC++ gain or lost, it depends on what kind of C/C++
code you run. I had a discussion with Ronald L on the VC++ Compiler team
about this and really, in some cases you gain performance running under
managed code. The most common case is that you will lose 2-7% with

Not correct. Managed code always has additional overhead over unmanaged
