I have a .NET Core solution (targetting a few platforms) and tried applying SourceLink to it, by adding the following to all the csprojs:
Quote: <PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>
<!-- Optional: Declare that the Repository URL can be published to NuSpec -->
<PublishRepositoryUrl>true</PublishRepositoryUrl>
<!-- Optional: Embed source files that are not tracked by the source control manager to the PDB -->
<EmbedUntrackedSources>true</EmbedUntrackedSources>
<!-- Optional: Include PDB in the built .nupkg -->
<AllowedOutputExtensionsInPackageBuildOutputFolder>$(AllowedOutputExtensionsInPackageBuildOutputFolder);.pdb</AllowedOutputExtensionsInPackageBuildOutputFolder>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.SourceLink.GitHub" Version="1.0.0-beta-62925-02" PrivateAssets="All"/>
</ItemGroup>
For the net461, netstandard2.0 targets NCrunch reported a build error (from the SourceLink .targets file I guess) that it couldn't work out where the git repo was.
That's understandable and maybe something to work around but kind of not NCrunch's fault.
However for the (much more simply-targetting) projects, they failed without error message, and NCrunch didn't stop the whole build/discovery process "properly".
