dotnet-trace report Missing Symbol for .Net 6 application in container even when pdb files are available

[t-bzhan]

Description

We have a .Net 6 application running in container with base image mcr.microsoft.com/dotnet/sdk:6.0-jammy. When using dotnet-trace to investigate a perf issue, we found that dotnet-trace reports a lot of functions as "Missing Symbol".

Opening the netrace file in Visual studio does not seem to work either, even when "Load All Symbols" is clicked.

I've checked that the pdb files are in the same directory with the dlls, could anyone suggest the next steps for further diagnosing?

Regression?

Hi @t-bzhan, can you try explicitly setting the symbol path to the folder containing the pdbs in visual studio? Debug-options-symbols

If that doesn't work then perhaps they are mismatched symbols

One update, I am able to view the call stack with Visual Studio 2022

Visual Studio 2019 did not work as I described in the issue.
