Very useful. I had no idea about eqatec and slimtune

dynaTrace supports .NET environments as well. It's not a profiler but an Application Performance Management Solution that gives you the ability to trace every single transaction in your application - not only on one CLR but across all CLRs you have in your system.
It also includes Memory Diagnostics to identify memory leaks and can tie these to individual transactions that cause the leak.

I'd also suggest the Commercial GlowCode ( which does performance and memory profiling for both .NET and Native code.
