Is it possible to retrieve line numbers corresponding to source code when throwing an exception for a Power Platform Plugin Package?

Background

• Plugin Packages are built as nuget packages and registered on against the Power Platform
• Packages are locked into .NET version net462 as an SDK style project
• Normally when throwing an exception, the stack trace is present, but line numbers are not
• In this process I’m building in debug mode

Code

• When using the following code: (link to github with full project below in the Links section)

            try
            {
                logic.ThrowException();
            }
            catch (Exception ex)
            {
                var stackTrace = new StackTrace(ex, true);
                var linenumber = stackTrace.GetFrame(0).GetFileLineNumber();
                var file = stackTrace.GetFrame(0).GetFileName();
                var method = stackTrace.GetFrame(0).GetMethod();
                localPluginContext.Trace($@"
                    {nameof(linenumber)}: {linenumber}, 
                    {nameof(file)}: {file}, 
                    {nameof(stackTrace)}: {stackTrace}");
            }

• I get the following trace output:

[+923ms] - [Execute] - Entered PluginStackTraceTest.StackTraceTestPlugin.Execute() Correlation Id: f12333aa-1894-4aa2-b5d5-f600e146e0ea, Initiating User: 1b4822ba-b1c5-eb11-8235-0022480a9839

What I’ve Tried

• I’ve added a Directory.Build.props file as specified in this SO Post: Include pdb files into my nuget (nupkg) files
• I’ve also set the properties in the .csproj file

  <PropertyGroup>
    <!-- Based on https://devblogs.microsoft.com/dotnet/producing-packages-with-source-link/ -->
    <!-- Publish the repository URL in the built .nupkg (in the NuSpec <Repository> element) -->
    <PublishRepositoryUrl>true</PublishRepositoryUrl>

    <!-- Embed source files that are not tracked by the source control manager in the PDB -->
    <EmbedUntrackedSources>true</EmbedUntrackedSources>
    <EmbedSources>True</EmbedSources>

    <!-- Embed symbols containing Source Link in the main file (exe/dll) -->
    <DebugType>embedded</DebugType>
    
    <ExcludeGeneratedDebugSymbol>False</ExcludeGeneratedDebugSymbol>
  </PropertyGroup>

• I’ve inspected the nuget package with dotpeek and confirmed that the pdb metadata is present in the package
• I’m assuming the metadata has been merged with the dll because when I unzip the package I see:
• I’ve also tried adding the parameter: <IncludeSymbols>true</IncludeSymbols> to the PropertyGroup, but then that just makes a separate symbols file:

Any suggestions / recommendations would be greatly appreciated and thanks in advance.
