CSPROJ & Nuget -> Dll 不会被复制到目标目录

问题描述 投票：0回答：1

我有一个项目，它创建一个 DLL，并在发布版本中创建一个 Nuget 包。

此包用于没有直接从 EXE 引用的插件中。该插件是动态加载的。

插件和 EXE 都位于解决方案中，并构建在同一目标目录中。

如果只有插件有对Nuget包的引用，则不会将对应的DLL复制到目标目录。一旦 EXE 本身收到对 Nuget 包的引用，依赖项就会被干净地复制到目标目录。

如何强制插件将依赖项复制到目标目录？

如果存在从 EXE 到所用包的直接引用或传递引用，则 dll 将被复制到目标目录。

Nuget包的CSPROJ：

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

  <PropertyGroup>
    <TargetFramework>net80-windows</TargetFramework>
    <AppendTargetFrameworkToOutputPath>true</AppendTargetFrameworkToOutputPath>
    <Product>PkgA</Product>
    <LangVersion>latest</LangVersion>
    <UseWindowsForms>true</UseWindowsForms>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <Configurations>Debug;Release</Configurations>
  </PropertyGroup>
  
  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
    <OutputPath>$(SolutionDir)bin\$(Configuration)</OutputPath>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <OutputPath>$(SolutionDir)bin\$(Configuration)</OutputPath>
    <Optimize>true</Optimize>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)'=='Release'">
    <GeneratePackageOnBuild>True</GeneratePackageOnBuild>
  </PropertyGroup>
  
  <PropertyGroup>
    <RestoreProjectStyle>PackageReference</RestoreProjectStyle>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
    <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
  </PropertyGroup>
  
  <ItemGroup Label="NuGetFileToCopy">
    <Content Include=".build\**" PackagePath="build\" />
    <Content Include=".build\**" PackagePath="buildTransitive\" />
    <Content Include="$(SolutionDir)\bin\$(Configuration)\net80-windows\$(Product).pdb" PackagePath="contentFiles\any\net8.0-windows7.0" PackageCopyToOutput="false" Visible="false" />
    <Content Include="$(SolutionDir)\bin\$(Configuration)\net80-windows\$(Product).xml" PackagePath="contentFiles\any\net8.0-windows7.0" PackageCopyToOutput="false" Visible="false" />
  </ItemGroup>

</Project>

使用插件的CSPROJ：

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

  <PropertyGroup>
    <TargetFramework>net80-windows</TargetFramework>
    <AppendTargetFrameworkToOutputPath>true</AppendTargetFrameworkToOutputPath>
    <UseWindowsForms>true</UseWindowsForms>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <Configurations>Debug;Release</Configurations>
  </PropertyGroup>
  
  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
    <OutputPath>$(SolutionDir)bin\$(Configuration)</OutputPath>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <OutputPath>$(SolutionDir)bin\$(Configuration)</OutputPath>
    <Optimize>true</Optimize>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="PkgA" Version="0.*" />
    <PackageReference Include="System.ComponentModel.Annotations" Version="5.0.*" />
    <PackageReference Include="System.ComponentModel.Composition" Version="8.*" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Contracts\Contracts.csproj" />
  </ItemGroup>

  <PropertyGroup>
    <RestoreProjectStyle>PackageReference</RestoreProjectStyle>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
    <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
  </PropertyGroup>

</Project>

Nuget 包还有一个 

targets
文件，它将 PDB 和 XML 复制到目标目录。这些文件已正确复制到目标目录。

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <!-- copy the files to the output directory -->
    <ItemGroup>
        <_PkgANet80Files Include="$(MSBuildThisFileDirectory)..\..\contentFiles\any\net8.0-windows7.0\*.*" />

        <!-- include everything -->
        <Content Include="@(_PkgANet80Files)">
            <Link>%(Filename)%(Extension)</Link>
            <Visible>False</Visible>
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
            <Pack>False</Pack>
        </Content>
    </ItemGroup>
</Project>

创建的

nuspec
-文件是：

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2013/05/nuspec.xsd">
  <metadata>
    <id>PkgA</id>
    <version>0.0.1.7</version>
    <authors>PkgA</authors>
    <description>Package Description</description>
    <repository type="git" commit="ad93ea6a6fa7ededfff35ea75fff94123661a768" />
    <dependencies>
      <group targetFramework="net8.0-windows7.0" />
    </dependencies>
    <frameworkReferences>
      <group targetFramework="net8.0-windows7.0">
        <frameworkReference name="Microsoft.WindowsDesktop.App.WindowsForms" />
      </group>
    </frameworkReferences>
    <contentFiles>
      <files include="any/net8.0-windows7.0/PkgA.pdb" buildAction="Content" copyToOutput="false" />
      <files include="any/net8.0-windows7.0/PkgA.xml" buildAction="Content" copyToOutput="false" />
    </contentFiles>
  </metadata>
</package>

原始 NuGet 包将包含本地项目 dll，如果您使用packages.config，则任何 nuget 包都将被列为依赖项。大家都很开心。

微软已经简化了一切，所以现在.Net（核心）一切都是从项目文件完成的，我更喜欢这一点。但现在使用 nuget pack，您生成的包将不会列出任何依赖项。

Microsoft 表示 NuGet 不支持 PackageReferences

NuGet CLI

所以你需要使用 dotnet pack 或 msbuild -t:pack

dotnet CLI

但是现在使用 dotnet pack，您可以为 PackageReferences 恢复依赖项，但您的 ProjectReferences 现在也被列为依赖项.....

下面是一个示例项目文件，其中包含 PackageReferences 和 ProjectReferences。对于项目，它们已被标记为 PrivateAssets="All"，然后使用自定义构建目标将项目所需的文件复制到包中。

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Title>Some.Project</Title>
  </PropertyGroup>

<ItemGroup>
  <PackageReference Include="Microsoft.Extensions.Something" Version="1.0.0" />
  <PackageReference Include="Newtonsoft.Json" Version="13.0.2" />
</ItemGroup>

<ItemGroup>
  <ProjectReference Include="..\Some.Other.Project.csproj" PrivateAssets="All" />
</ItemGroup>

<PropertyGroup>
  <TargetsForTfmSpecificBuildOutput> $(TargetsForTfmSpecificBuildOutput);CopyProjectReferencesToPackage</TargetsForTfmSpecificBuildOutput>
</PropertyGroup>

<Target Name="CopyProjectReferencesToPackage" DependsOnTargets="BuildOnlySettings;ResolveReferences">
  <ItemGroup>
  <_ReferenceCopyLocalPaths Include="@(ReferenceCopyLocalPaths->WithMetadataValue('ReferenceSourceTarget', 'ProjectReference')->WithMetadataValue('PrivateAssets', 'All'))"/>
  </ItemGroup>

  <ItemGroup>
    <BuildOutputInPackage Include="@(_ReferenceCopyLocalPaths)" TargetPath="%(_ReferenceCopyLocalPaths.DestinationSubDirectory)"/>
  </ItemGroup>
</Target>
</Project>

使用 PackageReference 时，NuGet pack 任务不包含依赖项 #10301 当使用 PackageReference 而不是 packages.config 时，nuget pack 忽略依赖项 #5979
