Snupkg not including PDB for a certain project ("The package does not contain any symbol (.pdb) files.")

[Piedone]

I'd like to publish the Lombiq UI Testing Toolbox for Orchard Core project on NuGet. This contains multiple csprojs that need to be packaged individually, referenced by the root sln file.

I get a "The package does not contain any symbol (.pdb) files." error when publishing the snupkg corresponding to the main Lombiq.Tests.UI project. And fair enough, the created snupkg doesn't contain a PDB, despite the build output (bin\Release\netcoreapp3.1) containing it. Any suggestions on how to fix this?

These are the commands I use to package all projects, run in the root of the repo (i.e. building the solution):

dotnet restore -p:NuGetBuild=True
dotnet build --configuration Release --no-restore -p:NuGetBuild=True -p:LangVersion=Latest -p:GenerateDocumentationFile=True -p:NoWarn=CS1573%3BCS1591%3BVSTHRD002%3BVSTHRD200 -p:EnableNETAnalyzers=false -p:ContinuousIntegrationBuild=true -p:DebugSymbols=true -p:DebugType=portable
dotnet pack --output artifacts --configuration Release --no-restore --no-build  -p:NuGetBuild=True -p:Version=0.0.10 -p:GenerateDocumentationFile=True -p:NoWarn=NU5104 -p:TreatWarningsAsErrors=true -warnaserror -p:WarnOnPackingNonPackableProject=True -p:IncludeSymbols=true -p:SymbolPackageFormat=snupkg

The other two Lombiq.Tests.UI.AppExtensions and Lombiq.Tests.UI.Shortcuts projects' snupkgs properly include their PDBs. Other projects of ours that I tried work too. There is something only with Lombiq.Tests.UI.

I noticed the same issue in this other project of ours. Both of them are testing-related, so maybe goes wrong related to that?

Thanks in advance!

It turns out that this is due to the project using Shouldly, since Shouldly overrides some necessary properties. Adding the following fixed the issue:

  <PropertyGroup>
    <Optimize>true</Optimize>
    <DebugType>portable</DebugType>
    <Deterministic>true</Deterministic>
    <DeterministicSourcePaths>true</DeterministicSourcePaths>
  </PropertyGroup>
