Lately there is a customer whos is very pessimistic about using .Net for making such applications as he has the strong notion that .Net Garbage collector plays spoilsport and interferes with communication timings and peformance and hence is pusing for a very large scale automation application to be done in VC++, and not using all the other benefits of .Net Can you please help provide some direction or links to articles/papers that have analysed .Net Garbage collector from this perspective, and if its really a problem using it in critical communication intensive applications ? I think otherwise and believe that if proper guidelines and practices are followed to avoid GC bottlenecks, its not a problem. But I have to prove the same with enough data and statistics.
