While we wait for my Groktalk to appear (editing is really hard and timeconsuming and Scott is a hero) I have been getting a few requests for “the seven things C++ has that C#” doesn't.
- Can generate native code and work with native types from other libraries 
- C++ interop – the fastest and easiest 
- Templates and generics 
- Deterministic destruction 
- my absolute favourite, I must say
 
- Optimized MSIL 
- PGO for native and managed code 
- .NET Linking (from within the IDE)
 
I will try to do individual blogs on these when I can. In the meantime, you can peruse the deck and remember, it's for a ten minute talk: Why Cpp.ppt (94 KB).
