Wix v4 HarvestProject not harvesting project references

[ian-g-holm-intel]

Can anyone tell me how to get HarvestProject to also harvest my project's references? Not matter what I do, my primary project's references do not get harvested.

Here is an example github project that reproduces this issue.

Harvest Element:

You might need to add a Harvest element to your property group:

<ItemGroup>
  <ProjectReference Include="MyProject.csproj" Harvest="true" … DoNotHarvest="true" />
</ItemGroup>

Version inside Package Reference:

I noticed you didn't include a version inside your package reference either:

<ItemGroup>
       <PackageReference Include="WixToolset.Util.wixext" />
       <PackageReference Include="WixToolset.Heat" />
   </ItemGroup>

Maybe changing it to look a bit more like this will help you:

 <ItemGroup>
       <PackageReference Include="WixToolset.Util.wixext" Version="<Version_Number>"/>
       <PackageReference Include="WixToolset.Heat" Version="<Version_Number>"/>
   </ItemGroup>

Misc.
In addition, it looks like you also have an extra parentheses within your the Condition of your PropertyGroup below:

<PropertyGroup Condition=" '$(Configuration))' == 'Debug' ">
        <DebugType>full</DebugType>
        <Optimize>false</Optimize>
    </PropertyGroup>

Full Disclosure, I'm more used to working with version 3 of the WiX toolset, so this advice might have been found in haste of trying to help you

I'm following the documentation for HarvestProject here, https://wixtoolset.org/docs/tools/heat/#using-harvestproject-to-harvest-output-from-a-project

When using HarvestProject, I don't think the ProjectReference should have Harvest="true".

My PackageReferences do not have versions specified because we're using ManagePackageVersionsCentrally and specifying them in a Directory.Packages.props file. The extra parenthesis was a mistake, but not the cause of my issues.

I've updated the description with a link to a github project that reproduces this issue. It includes 3 parojects, ExampleApp, ExampleLibrary and ExampleMsi. The ExampleMsi harvests ExampleApp and ExampleApp references ExampleLibrary. The HarvestProject is only harvesting ExampleApp.exe but not ExampleLibrary.dll.
