That's a nice memory profiler, have good success with it. I've also used DebugDiag, https://www.microsoft.com/en-us/download/details.aspx?id=499... and plain ol' perfmon and its performance counters, to help track down GC-related issues.

Agreed. Starting point PerfMon and PerfCounters, as an addition to great suggested profilers I would also have a look at PerfView / ETW.
