c# - 验证解决方案项目之间没有文件引用

Question

假设 .NET 解决方案中有两个项目:

Solution
    - Project1
    - Project2

我只想拥有从 Project2 到 Project1 的 Project References，例如:

<ItemGroup>
  <ProjectReference Include="Project1.csproj" />
</ItemGroup>

但有时开发人员会添加错误的 File References 而不是:

<ItemGroup>
  <Reference Include="Project1">
    <HintPath>path\to\Project1.dll</HintPath>
  </Reference>
</ItemGroup>

我如何确定解决方案项目之间没有文件引用？理想情况下，它应该是构建错误，但实现它的最佳方法是什么？

Answer 1

我找到了解决方案。可以添加 MSBuild 任务(目标)来检查所有解决方案项目的文件引用。此任务必须添加到所有项目或 Directory.Build.targets。这是目标:

<Project>
  <Target Name="BeforeBuild">
    <Message Text="Analyzing '$(MSBuildProjectFile)' for file references between solution projects...&#xA;" />

    <GetSolutionProjects Solution="$(MSBuildThisFileDirectory)\YourSolutionName.sln">
      <Output ItemName="Projects" TaskParameter="Output"/>
    </GetSolutionProjects>

    <PropertyGroup>
      <Expression>(@(Projects->'%(ProjectName)', '|')).dll</Expression>
    </PropertyGroup>

    <XmlRead XmlFileName="$(MSBuildProjectFile)" XPath="//Project/ItemGroup/Reference/HintPath">
      <Output ItemName="FileReferences" TaskParameter="Value"/>
    </XmlRead>

    <RegexMatch Input="@(FileReferences)" Expression="$(Expression)">
      <Output TaskParameter="Output" ItemName ="ProjectReferences" />
    </RegexMatch>

    <Error Text="There must be no file references between solution projects, but it was found in '$(MSBuildProjectFile)' to the following file(s): %(ProjectReferences.Identity)"
           Condition="'%(ProjectReferences.Identity)' != ''" />
  </Target>
</Project>

此目标使用 MSBuild Community Tasks因此不要忘记将此 NuGet 包添加到您的所有项目中(或添加到 Directory.Build.props)。
