为何dotnet build与dotnet pack生成的nupkg包不一致？

我有一个打包为NuGet包的源代码生成器，需将YamlDotNet作为私有资产捆绑到分析器中，对应的csproj配置如下：

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

    <PropertyGroup>
        <TargetFramework>net7.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>

    </PropertyGroup>

    <ItemGroup>
        <None Include="../../README.md" Pack="true" PackagePath="\" />
    </ItemGroup>

        <PackageReference Include="YamlDotNet" Version="13.1.0" PrivateAssets="all" GeneratePathProperty="true" />
    </ItemGroup>
    
    <!-- Gross hack to let source generator use nuget packages -->
    <PropertyGroup>

    </PropertyGroup>
    
    <Target Name="GetDependencyTargetPaths" AfterTargets="ResolvePackageDependenciesForBuild">
            <ItemGroup>
                <TargetPathWithTargetPlatformMoniker Include="@(ResolvedCompileFileDefinitions)" IncludeRuntimeDependency="false" />
                <None Include="@(ResolvedCompileFileDefinitions)" Pack="true" PackagePath="analyzers/dotnet/cs" Visible="false" />
            </ItemGroup>
    </Target>

    <ItemGroup>
        <None Include="$(OutputPath)\$(AssemblyName).dll" Pack="true" PackagePath="analyzers/dotnet/cs" Visible="false" />
    </ItemGroup>
</Project>

使用命令dotnet pack -c Release生成的nupkg包包含所有预期的依赖DLL：

❯ unzip -l SuperFluid.0.0.1-alpha.nupkg                                                                                                   ─╯

但使用命令dotnet build -c Release && dotnet pack -c Release -p:PackageVersion=0.0.2生成的nupkg包中，这些依赖DLL被剥离：

❯ unzip -l SuperFluid.0.0.2.nupkg                                                                                                         ─╯

    29800                     6 files

目前我可通过GeneratePackageOnBuild规避此问题，但仍有两个疑问：

• 为何两种方式生成的nupkg包不一致？
• 如何让dotnet pack命令包含私有资产？

（注：我知晓源代码生成器理论上应针对netstandard 2.0，但此为另一问题，我有自己的考量）
