Hi,
i was having index out of bound problem with the new instrumentation type. I was using the legacy one and it worked completely. Since 4.9, access to the legacy instrumentation is not possible anymore and i have the same problem in vs 2022 as in vs 2019.

Here is the stack trace:

Hi, thanks for sharing this problem.

This looks to be caused by a hole in our CIL handling. The type mentioned in the error descends from a type declared in another assembly that doesn't seem to fit the CIL structure expected by NCrunch. I'm wondering if it might have been manipulated/obfuscated somehow or built with a niche compiler. Is this base type declared in a package that is available online? If I can reproduce this issue I hope it should be straightforward to fix it.

Hi, Thanks for the quick answer. Nothing have been obfuscated on our side. The problematic class is a derivation from the base class in a Google library named GoogleAdsConfig.cs

This class is included in the package https://www.nuget.org/pa...gle.Ads.GoogleAds/6.0.0

The source of it can be found here: is https://github.com/googleads/google-ads-dotnet

Thanks

Thanks for these details.

I can confirm that I can now reproduce this problem at will using the specified library.

I will let you know as soon as we have a fix available.

Ok, I can confirm you that its working for vs 2022, i will be soon able to test it with vs 2019. From my point of view, it seem to be fixed!

Thanks
