I tries to collect profiling data of my ASP.NET Core 3.1 app on Ubuntu with "dotnet-trace collect" and view this data with PerfView but got only unmanaged code results.

What am I doing wrong? The app is definitely a managed app. Thank you!

  • Did you manage to get answer? Maybe libraries you are using call unmanaged code? Or this is time spent in CLR? – GrayCat Jan 21 '21 at 19:31

It looks like you are missing symbols. Can you right click on lines with question marks and click 'Lookup Symbols' and see what you get?
