Is it possible to recover the source code of a nuget package built with EmbedAllSources enabled?

I am building a nuget package from a new-format-csproj project. I included the EmbedAllSources property (see below) in my csproj file: 

...
<PropertyGroup>
  <!-- Omitted for brevity --> 
  <GeneratePackageOnBuild>true</GeneratePackageOnBuild>
  <IncludeSymbols>true</IncludeSymbols>
  <EmbedAllSources>true</EmbedAllSources>
  <!-- Omitted for brevity --> 
</PropertyGroup>
...

Is it possible that consumers of my nuget, retrieve/reconstruct the source code of my nuget because of that property? If so, how?

Solution

  • Yes.

    Running this with dotnet core 3.1.201 and a minimal test project, I end up with a .nupkg and a .symbols.nupkg in the output folder. These files are just zips, so unzip them in any way you like. The .symbols.nupkg file contains the .pdb file under /libs/{framework}/. I didn't even try to do anything clever... just chucked it into notepad++ and you can see clearly that all the relevant source is in there. Extracting it into individual .cs files will take a bit more effort, but not too much more.
