We are recently upgraded a web/mvc application to use StrucutreMap 3.0.4

Now, when attempting to profile the application using RedGate Ant's profiler at the "Line Level Timings, All Methods with Source" or greater level, we get the following error

Operation could destabilize the runtime.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Security.VerificationException: Operation could destabilize the runtime.

Source Error:

I've tried adding to system.web in web.config as per http://documentation.red-gate.com/display/APP8/Operation+could+destabilize+the+runtime+error+profiling+ASP.NET

  • Another solution to get rid of this exception, is to [add the assembly-in-concern to the "LineLevelBlacklist.xml" file](https://forums.red-gate.com/viewtopic.php?p=138072#p138072). – Uwe Keim Dec 26 '16 at 18:52

May be an old question, but it's still one of the first for me on google results, so here goes.

I was able to solve the issue by deleting structuremap's pdb files before profiling.

Added <assemblyName>StructureMap</assemblyName> to %LOCALAPPDATA%\Red Gate\ANTS Performance Profiler 9\LineLevelBlacklist.xml which did the trick.

I was able to work around the problem by adding the following to the AssemblyInfo.cs of the class library causing the problem.

[assembly: System.Security.SecurityRules(System.Security.SecurityRuleSet.Level1)]

I found this solution in a Redgate forum discussion.
