Unsupported language/version ? #214

Open manson opened 1 year ago

manson commented 1 year ago

Environment:

I have an ASP.NET big application with multiple sub projects (libraries). I have implemented a separate library Tracing with all aspects and attributes implementation. Next I have added reference to this project from main app and started testing, It worked well until I have finished the needed logic and applied attributes to all the classes I need to intercept behavior with AspectInjector. And after spending the whole day doing this, I got next error on building my app.

The same for 2.8.2

Don't know even what to think.

UPD. I don't know what happened (I spent a day finding error reason) but everything has fixed after I have added the new subproject (class library) into the solution for testing, applied attributes to it, built. It built ok, but after I checked the main project and it built as well! Now everything works well - I cleanup solution, rebuild and it works... Don't know what to think. Hope later it wont face the same issue...

UPD No, it do not work. It just reference to aspect library in this project dropped and hence was not doing any injection and so build without errors....

UPD Figured out where this happened, but not why. This is an ordinary class where putting attributes on it raising that error. I have about 30 classes with this aspect attributes and similar classes and only on this class it breaks. Cannot get how it differ from others. Temporarilly removed attributes from this class, let it be unwachable for a while. If you have any ideas whould be greatfull...

Hey @manson , thatnk you for the report and sorry for the delay. Would it be possible to share the code of the affected classs?
