I did a 10 minute presentation on a WPF application architecture using C++/CLI as a ViewModel to wrap a pure C backend, at the DevJam held by the Perth .Net Community of Practice. Here are the slides in PDF and PPTX format including a few notes which cover the points I made verbally.

I’ve been doing a huge amount of work recently porting the C++ OOFILE report writer to REALbasic as a complete transliteration, having given up on the earlier report-writer I was writing from scratch.
I’m using REALbasic 2008r4.1 and finding it extremely flaky when debugging. I finally worked out the cause and it’s an interesting trap.
OOFILE was written about 15 – 10 years ago and makes use of lots of inline and non-virtual functions for high-performance in C++. Methods in REALbasic are, of course, all virtual but it also has Computed Properties which allow you to write code as getter and setter functions. These are non-virtual and therefore (presumably) much faster – an ideal and idiomatic match for the inline getters and setters used heavily in OOFILE.
However, there’s one very big gotcha – if you look at an object in the REALbasic debugger, all its getters on computed properties are executed.
