Profiling ASP.NET: Operation could destabilize the runtime

[jaap.q42]

I have a depency on Common.Logging.2.1.0.0 which wasn't release so I built it myself from github.

I'm getting the VerificationException Operation could destabilize the runtime. exception which I've already found on these forums.

Running IIS7 on Windows 7 .NET 4, using ANTS Performance Profiler 6.3 Prof.

I've been able to do this:
* <system.web><trust level="Full"/>
* got profiling working with method timings only
* Altered The Common.Logging dll (since I already built it myself) to include [assembly: System.Security.SecurityRules(System.Security.SecurityRuleSet.Level1)] instead of [assembly: SecurityTransparent]

The line which was reported by the exception seems stange:
Line 86: public static readonly string COMMON_LOGGING_SECTION = "common/logging";
although ANTS might be doing things there to make the line numbers all weird.

I found a [assembly: AllowPartiallyTrustedCallersAttribute()] in the code.
However,

DELETING the PDB files worked, obviously, because I only want methods with source, so when I removed the pdb file, ANTS has no way to find the source!

This is a well known issue but I believe the very latest update to ANTS improves the situation, bypasssing assemblies thus marked (without needing to delete any PDBs). Please can you upgrade and retry?

Unfortunately upgrading is not an option because we didn't renew our license. I consider the issue closed since the fix is not to include pdb's which is just fine, I don't need them anyway...
