Major issue with Performance Profiler

Hello

We have a massive issue with the profiler

Does anyone know how to resolve the error below?

System.MethodAccessException: Attempt by security transparent method 'System.Net.Http.HttpClient.FinishSendAsyncBuffered(System.Threading.Tasks.Task`1<System.Net.Http.HttpResponseMessage>, System.Net.Http.HttpRequestMessage, System.Threading.CancellationTokenSource, Boolean)' to call native code through method '<Module>._ANTS_Begin_Async()' failed.  Methods must be security critical or security safe-critical to call native code.

Its hard to know exactly where the call is coming from without a log file but;

• If the offending DLL is your own code, you can try just removing the [AllowPartiallyTrustedCallers] attribute (if present)

• You can disable async profiling (Tools>Advanced Options> Profile with Async awareness)

• Or you can keep the async profiling option turned on and also avoid the error if you add the offending dll to the profiler's line-level blacklist. You can do this by adding the following line to the LineLevelBlacklist.xml file in %localappdata%\Red Gate\ANTS Performance Profiler 10
