Opinionated MSBuild package for authoring source NuGet packages using standard SDK dotnet pack.

• Ships .cs files under contentFiles/cs/{tfm}/... with BuildAction=Compile
• Optional build/{tfm}/*.props and *.targets via SourcePackFile
• Optional SourcePackBundle for meta-packages that re-export dependency source/build assets
• Per-target-framework dependencies from plain PackageReference items
• No lib/ output (IncludeBuildOutput=false by default)
• Works with class libraries, console apps, and Azure Functions source projects

Add a development dependency to the project you want to pack:

<PackageReference Include="Devlead.SourcePack" PrivateAssets="all" />

<PropertyGroup>
  <TargetFrameworks>net8.0;net9.0;net10.0</TargetFrameworks>
  <SourcePackRoot>Devlead/MyPackage</SourcePackRoot>
  <IsPackable>true</IsPackable>
</PropertyGroup>

<PackageReference Include="Devlead.SourcePack" PrivateAssets="all" />

<SourcePackFile Include="MyPackage.props" Kind="Build" />
<SourcePackFile Include="MyPackage.targets" Kind="Build" />
<SourcePackFile Include="../../README.md" Kind="Metadata" />

Pack in Release:

dotnet pack -c Release

For multi-target projects (TargetFrameworks), pack single-threaded to avoid duplicate contentFiles entries:

dotnet pack -c Release -- /m:1

Devlead.SourcePack sets BuildInParallel=false as an additional safeguard.

Re-export source and build assets from a restored dependency package into your nupkg (meta-packages / vendoring).

Add a matching PackageReference (with GeneratePathProperty="true" recommended). Bundle paths are resolved from project.assets.json, so central package management works without Version on the reference:

<PackageReference Include="Devlead.SourcePack.Sample"
                 PrivateAssets="all"
                 GeneratePathProperty="true"
                 Pack="false" />

<SourcePackBundle Include="Devlead.SourcePack.Sample"
                  PackagePathPrefix="Devlead/Bundled" />

Example output paths when bundling Devlead.SourcePack.Sample with prefix Devlead/Bundled:

• contentFiles/cs/net8.0/Devlead/Bundled/Devlead/Sample/SampleService.cs
• build/net8.0/Devlead.SourcePack.Sample.props

dotnet run --file cake.cs

• Devlead.Console
• Devlead.Testing.MockHttp
