Here's my wish list:
1) The examples are a start, but I would like to see more on extending the Desktop
2) Preserve all of the 9.3 C++ material and discussions (e.g. working with events) as well as examples
3) Convert all of the 9.3 "C++" VB6 snippets to actual C++
4) Will the add-in framework support C++? Currently it only supports .NET and Java
Why my emphasis on C++? Because .NET (or Python) performance is about three and a half times slower working with fine-grained ArcObjects. When I first migrated some VBA apps to .NET, everyone complained until I moved the non-GUI components to C++. Ideally, I'd like to drop .NET altogether, because cross-platform applications are messier to debug and distribute. [Yes, I tried C++/CLI, and the performance of unmanaged code was HORRIBLE!] OK, enough ranting for today. 😉
