I didn't use it myself above and beyond installing and having a quick play - it wasn't what I needed for the project. That's not to say it was no good, just didn't fit what I wanted. Just one caveat - downloading the demo obviously put me onto some sort of marketing list - I got bombarded with phone calls and emails from them afterwards - not the usual spam per-se, but more "how can we help you decide to buy" type things - still irritating though. C# has already designed away most of the tedium of C++.
