在项目编译成 dll 之前，如何分析项目的所有依赖呢？可以在在项目的 Target 中去收集项目的依赖。

本文将说明如何在 Target 中收集项目依赖的所有 dll 的文件路径。

编写 Target

<Target Name="WalterlvDemoTarget" BeforeTargets="CoreCompile">
    <Message Text="References:" />
    <Message Text="@(Reference)" />
  </Target>

这个 Target 的作用是将项目的所有 Reference 节点作为集合输出出来。然而实际上如果真的编译这个项目，会发现我们得到的结果有一些问题：

实际上其值就是写到每一个 Reference 里面的字符串的集合
- 比如引用了 System.Xaml，那么这里就会是 System.Xaml
如果引用是通过 ProjectReference 进行的项目引用，那么这里就没有目标项目的 dll

所以，我们需要一个新的属性来查找引用的 dll。通过研究 Microsoft.NET.Sdk 的源码，我发现有 ReferencePath 属性可以使用，于是将 Target 改为这样：

<Target Name="WalterlvDemoTarget" BeforeTargets="CoreCompile;ResolveAssemblyReference">
    <Message Text="ReferencePaths:" />
    <Message Text="@(ReferencePath)" />
  </Target>

现在得到的所有依赖字符串则没有以上的问题。

注意，我在 BeforeTargets 上增加了一个 ResolveAssemblyReference 。

以上 Target 的输出

引用通常很多，所以我将以上的输出单独放到这里来，避免影响到上面一节知识的阅读。

Reference 的输出

可以看到，Reference 的输出几乎就是 Reference 中写的字符串本身。

ReferencePath 的输出

可以看到，ReferencePath 则是将所有的 dll 的路径也输出了，而且即便是项目引用，项目编译好的 dll 的路径也在。

解读原因

解析引用的 dll 的路径的 Task 是 ResolveAssemblyReference ，你可以在 Microsoft.NET.Sdk 文件夹中找到它。如果想知道 Task 是什么意思，可以阅读：理解 C# 项目 csproj 文件格式的本质和编译流程。

<ResolveAssemblyReference
    Assemblies="@(Reference)"
    AssemblyFiles="@(_ResolvedProjectReferencePaths);@(_ExplicitReference)"
    TargetFrameworkDirectories="@(_ReferenceInstalledAssemblyDirectory)"
    InstalledAssemblyTables="@(InstalledAssemblyTables);@(RedistList)"
    IgnoreDefaultInstalledAssemblyTables="$(IgnoreDefaultInstalledAssemblyTables)"
    IgnoreDefaultInstalledAssemblySubsetTables="$(IgnoreInstalledAssemblySubsetTables)"
    CandidateAssemblyFiles="@(Content);@(None)"
    SearchPaths="$(AssemblySearchPaths)"
    AllowedAssemblyExtensions="$(AllowedReferenceAssemblyFileExtensions)"
    AllowedRelatedFileExtensions="$(AllowedReferenceRelatedFileExtensions)"
    TargetProcessorArchitecture="$(ProcessorArchitecture)"
    AppConfigFile="@(_ResolveAssemblyReferencesApplicationConfigFileForExes)"
    AutoUnify="$(AutoUnifyAssemblyReferences)"
    SupportsBindingRedirectGeneration="$(GenerateBindingRedirectsOutputType)"
    IgnoreVersionForFrameworkReferences="$(IgnoreVersionForFrameworkReferences)"
    FindDependencies="$(_FindDependencies)"
    FindSatellites="$(BuildingProject)"
    FindSerializationAssemblies="$(BuildingProject)"
    FindRelatedFiles="$(BuildingProject)"
    Silent="$(ResolveAssemblyReferencesSilent)"
    TargetFrameworkVersion="$(TargetFrameworkVersion)"
    TargetFrameworkMoniker="$(TargetFrameworkMoniker)"
    TargetFrameworkMonikerDisplayName="$(TargetFrameworkMonikerDisplayName)"
    TargetedRuntimeVersion="$(TargetedRuntimeVersion)"
    StateFile="$(ResolveAssemblyReferencesStateFile)"
    InstalledAssemblySubsetTables="@(InstalledAssemblySubsetTables)"
    TargetFrameworkSubsets="@(_ReferenceInstalledAssemblySubsets)"
    FullTargetFrameworkSubsetNames="$(FullReferenceAssemblyNames)"
    FullFrameworkFolders="$(_FullFrameworkReferenceAssemblyPaths)"
    FullFrameworkAssemblyTables="@(FullFrameworkAssemblyTables)"
    ProfileName="$(TargetFrameworkProfile)"
    LatestTargetFrameworkDirectories="@(LatestTargetFrameworkDirectories)"
    CopyLocalDependenciesWhenParentReferenceInGac="$(CopyLocalDependenciesWhenParentReferenceInGac)"
    DoNotCopyLocalIfInGac="$(DoNotCopyLocalIfInGac)"
    ResolvedSDKReferences="@(ResolvedSDKReference)"
    WarnOrErrorOnTargetArchitectureMismatch="$(ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch)"
    IgnoreTargetFrameworkAttributeVersionMismatch ="$(ResolveAssemblyReferenceIgnoreTargetFrameworkAttributeVersionMismatch)"
    FindDependenciesOfExternallyResolvedReferences="$(FindDependenciesOfExternallyResolvedReferences)"
    ContinueOnError="$(ContinueOnError)"
    Condition="'@(Reference)'!='' or '@(_ResolvedProjectReferencePaths)'!='' or '@(_ExplicitReference)' != ''"
    >

    <Output TaskParameter="ResolvedFiles" ItemName="ReferencePath"/>
    <Output TaskParameter="ResolvedFiles" ItemName="_ResolveAssemblyReferenceResolvedFiles"/>
    <Output TaskParameter="ResolvedDependencyFiles" ItemName="ReferenceDependencyPaths"/>
    <Output TaskParameter="RelatedFiles" ItemName="_ReferenceRelatedPaths"/>
    <Output TaskParameter="SatelliteFiles" ItemName="ReferenceSatellitePaths"/>
    <Output TaskParameter="SerializationAssemblyFiles" ItemName="_ReferenceSerializationAssemblyPaths"/>
    <Output TaskParameter="ScatterFiles" ItemName="_ReferenceScatterPaths"/>
    <Output TaskParameter="CopyLocalFiles" ItemName="ReferenceCopyLocalPaths"/>
    <Output TaskParameter="SuggestedRedirects" ItemName="SuggestedBindingRedirects"/>
    <Output TaskParameter="FilesWritten" ItemName="FileWrites"/>
    <Output TaskParameter="DependsOnSystemRuntime" PropertyName="DependsOnSystemRuntime"/>
    <Output TaskParameter="DependsOnNETStandard" PropertyName="_DependsOnNETStandard"/>
</ResolveAssemblyReference>

从这个 Task 中可以看出，它还输出了以下这些属性或集合：

ReferenceDependencyPaths
ReferenceSatellitePaths
ReferenceCopyLocalPaths
- 这是需要拷贝到本地的那些 dll 的路径（不含框架自带的 dll）
SuggestedBindingRedirects
FileWrites
- 要写入的一些缓存文件
DependsOnSystemRuntime
- 以上都是集合，唯独这是一个布尔值，表示是否依赖系统运行时
