I'm currently profiling an ASP.NET MVC application. We're seeing that the "% Time in RT Checks" counter is very high. I understand this means we are passing a lot of time in CAS checks, but I'm having difficultly pin pointing what code is making this CAS checks. We do very little native interop, so it does come from that. What other framework calls are verified by CAS? Are there any techniques for finding which calls are causing this?
Many thanks,
Robert
