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

我只想从项目2到项目1 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，例如：

<ItemGroup>
  <Reference Include="Project1">
    <HintPath>pathtoProject1.dll</HintPath>
  </Reference>
</ItemGroup>

如何确定解决方案项目之间没有File References？理想情况下，它应该是一个构建错误，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），以检查所有解决方案项目中的文件引用。必须将此任务添加到所有项目或Directory.Build.targets 中。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 社区任务，因此不要忘记将此 NuGet 包添加到所有项目（或Directory.Build.props）。

你可以写一个简单的PowerShell

$path = "D:tempSolution1"
$extension = "csproj"

#-------------------
$projects = Get-ChildItem -Path $path -Recurse -Filter "*.$($extension)"
$projectsList = @()
# Create the project's solution list
foreach ($project in $projects)
{
    $projectsList += $project
}

foreach($project in $projectsList)
{   
    # Read the project xml
    [xml]$proj = [System.IO.File]::ReadAllText($project.FullName)
    # loop throught ItemGroup
    foreach($item in $proj.Project.ItemGroup)
    {
        # Looking for project reference
        $all = $projectsList | where {$_.Name -eq "$($item.Reference.Include).$($extension)"} 
        foreach($ref in $all)
        {
            Write-Warning "Find wrong reference for $($ref.Name) on $($project.Name)"
        }
    }
}
