自动构建 NuGet 包，包括引用的依赖项

Your point #3 (Add references to various .dll files/other projects <-- this is the missing part) really contains two different issues: (1) add references to various dll files, and (2) add references to other projects in the same solution.

Number (2) here has gotten some added support as of NuGet 2.5. You can add an option to include references to other projects in the same solution when creating a NuGet package for a project:

nuget pack projectfile.csproj -IncludeReferencedProjects

• If projectfile.csproj references any other projects in your solution that also is exposed as NuGet packages, these projects' NuGet packages will be added as dependencies.
• If it references projects in your solution that doesn't expose themselves as NuGet packages, their dlls will be included in this NuGet package.

As for (1), if you find yourself often adding dlls to your projects that aren't available as NuGet packages, you could just create your own (internal) NuGet packages with these files. If you then add these dlls as a NuGet package instead of the files directly, this NuGet package will be a dependency in your project's NuGet package.

For other Googlers, you can use this if you are using the NuGet.targets file to run NuGet Pack:

<Target Name="PrePackage" BeforeTargets="BuildPackage">
<PropertyGroup>
<BuildCommand>$(BuildCommand) -IncludeReferencedProjects</BuildCommand>
</PropertyGroup>
</Target>

The solution which I found is an extension for Visual Studio: https://visualstudiogallery.msdn.microsoft.com/fbe9b9b8-34ae-47b5-a751-cb71a16f7e96/view/Reviews

You simply add new project called NuGet Package:

Then you are adding interesting you projects to references and BOOOM !! All dependencies and file directories are automatically added. If you want to modify NuSpec data you click right at project and go to Properties, then modify what you want. Generated NuSpec and nupkg will be in folder obj of your new project. I hope it helps ;).

I found a well-written article on this topic. I have the same issue with certain packages that have a hierarchy of dependencies and up until now I've been uploading each as a separate NuGet package (what. a. waste. of. time)

I've just tested the solution found here: https://dev.to/wabbbit/include-both-nuget-package-references-and-project-reference-dll-using-dotnet-pack-2d8p

And after examining the NuGet package using NuGet Package Explorer, the DLLs produced by referenced projects are indeed present. I'm going to test by actually submitting this package to NuGet and testing it.

Here's my source in case it is helpful to you: https://github.com/jchristn/NuGetPackTest

And the test NuGet package: https://www.nuget.org/packages/NuGetPackTest/1.0.0

The solution appears to work well. I don't know what it's going to look like when there are layers of references, I'm sure it could get really hairy and really fast.

.csproj from NuGetPackTest library which references project TestLibrary (portions removed for brevity)

<Project Sdk="Microsoft.NET.Sdk">
 

<PropertyGroup>
<TargetFrameworks>netstandard2.0;netcoreapp3.0;netcoreapp3.1;net461</TargetFrameworks>
...
<GeneratePackageOnBuild>true</GeneratePackageOnBuild>


<!-- added this line -->
<TargetsForTfmSpecificBuildOutput>$(TargetsForTfmSpecificBuildOutput);CopyProjectReferencesToPackage</TargetsForTfmSpecificBuildOutput>
</PropertyGroup>


<ItemGroup>


<!-- modified this ProjectReference to include the children ReferenceOutputAssembly and IncludeAssets -->
<ProjectReference Include="..\TestLibrary\TestLibrary.csproj">
<ReferenceOutputAssembly>true</ReferenceOutputAssembly>
<IncludeAssets>TestLibrary.dll</IncludeAssets>
</ProjectReference>
</ItemGroup>


<!-- added this section -->
<Target DependsOnTargets="ResolveReferences" Name="CopyProjectReferencesToPackage">
<ItemGroup>
<BuildOutputInPackage Include="@(ReferenceCopyLocalPaths->WithMetadataValue('ReferenceSourceTarget', 'ProjectReference'))"/>
</ItemGroup>
</Target>
  

</Project>

I solved this for my case by adding the whole TargetDir to the nuget package. Just add this to the .csproj :

<Target Name="IncludeAllFilesInTargetDir" AfterTargets="Build">
<ItemGroup>
<None Include="$(TargetDir)\**">
<Pack>true</Pack>
<PackagePath>tools</PackagePath>
</None>
</ItemGroup>
</Target>
