Docker Compose Not Allowing External Library Debugging

Question

I'm trying to debug an inhouse library while running my application in a container using docker-compose.

I've setup the internal library with the following settings as per the SourceLink documentation SourceLink. I am publishing the NUGET package to Azure Devops Artifact.

I can debug the external library when running the project and I can see .pdb files are loaded in the Debugging Modules window. The symbol file is also in the correct symbolCache location

C:\Users\darrent\AppData\Local\Temp\SymbolCache\LAWFORALL.Seedwork.pdb\3ca3000ecd7b49ae82c712ab8757040effffffff\LAWFORALL.Seedwork.pdb

When running the same project using docker-compose I cannot step into the library and symbols aren't loaded.

Below is an extract on my package using Nuget Package Explorer

Below is the configuration that resides in the .csproj file of my package.

<PropertyGroup>
        <AllowedOutputExtensionsInPackageBuildOutputFolder>$(AllowedOutputExtensionsInPackageBuildOutputFolder);.pdb</AllowedOutputExtensionsInPackageBuildOutputFolder>
        <EmbedUntrackedSources>true</EmbedUntrackedSources>
        <ContinuousIntegrationBuild>true</ContinuousIntegrationBuild>
        <PublishSymbols>true</PublishSymbols>
        
        <PublishRepositoryUrl>true</PublishRepositoryUrl>
        <IncludeSymbols>true</IncludeSymbols>
        <SymbolPackageFormat>symbols.nupkg</SymbolPackageFormat>
    </PropertyGroup>

<ItemGroup>
    <PackageReference Include="Microsoft.SourceLink.AzureRepos.Git" Version="1.1.1" PrivateAssets="All"/>
</ItemGroup>

My debugging settings in the project are as follows.

I've added the Azure Devops as a Symbol location as per the image below.
