I am trying to run casll graph profiling for an ASP.NET application built on .NET 2.0. I am always getting: " System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. " when i run with profiler. The application runs fine without profiler or when i run sampling. But, I need to run call graph wizard to more deeply understand slow running functions. Are there any know issues with .NET 2.0? I am running RTM version of .NET 2.0, not beta. I have unregistered ASP.NET 1.1 to check if it helps, but i still get the same problem.
