Yeah, I've had to push code down from our C# layer to our C++ layer on more than one occasion because the GC wasn't freeing memory promptly enough. I guess I don't know the GC well enough to nudge it in the right direction - but now I don't trust it and I plan to keep all high performance stuff in the native layer. I'd like to hear from someone who figured out how to tame the GC in applications where lots of new data is created and destroyed quickly.
