Msbuild directory.build.props：将存储在多级文件夹中的外部内容文件正确链接到.csproj

在度过了几天之后，我来到这里寻求帮助

情况是这样的——由于git存储库的大小增加，我们的构建占用了太多的时间。在进行构建之前，大部分时间都花在拉取一大组文件上。在进行构建之前，我们的Jenkins工作流将清除工作区，以确保不存在上一个构建的残余。事实证明，这些大型内容文件不会经常更改。因此，我将它们分离到一个不同的目录中，该目录与我现有的源代码文件具有类似的文件夹结构。这些内容文件保存在不同的存储库中，仅在需要时才提取。下面是我的文件夹结构：

    **ContentFiles**
       \ConsoleApp1\Content\TestData
                               New Bitmap Image.bmp
                               abc.xyz
                               cosoleDep1.txt
       \Model\ConsoleApp2\Files
                          readme.txt
                          readme2.txt
       \Model\Tools\ConsoleApp3\Packages
                                New Bitmap Image.bmp
                                New Text Document.txt
    **Sources**
       \ConsoleApp1
                    ConsoleApp1.csproj
       \Model\ConsoleApp2
                    ConsoleApp2.csproj
       \Model\Tools\ConsoleApp3
                    ConsoleApp3.csproj
       ConsoleApp1.sln
       Directory.Build.props

现在，我们来制作构建程序，将其中一些文件包含在源项目文件.csproj中，另一些文件包含在各自的输出文件夹中，以便进行打包和单元测试。我选择的选项是使用Directory.Build.props文件根据需要构建链接。因此，使用以下脚本在源代码的根级别添加了Directory.Build.props

<Project  xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

    <PropertyGroup>
        <ContentFilesDir>$(MSBuildThisFileDirectory)\ContentFiles\</DependencyDir>
    </PropertyGroup>

    <ItemGroup>
        <ContentFiles Include="$(ContentFilesDir)\**\$(MSBuildProjectName)\**\*.*"/>
    </ItemGroup>

    <ItemGroup>
       <Content Include="@(ContentFiles)"  >
            <Link>%(RecursiveDir)\%(Filename)%(Extension)</Link>
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
            <Visible>True</Visible>
        </Content>

    </ItemGroup>
</Project>

这里感兴趣的行是过滤器和 %RecursiveDir\%Filename%扩展名。我相信%RecursiveDir正在从列表中检索该项，并且名称从包含项目名称的最后一个反斜杠开始。因此，它正在处理的列表必须采用正确的格式。当项目处于多级文件夹结构中时，如何修改过滤器以删除该级别

必须有要求：内容文件必须在项目中显示为各个项目中的链接文件。如果我使用任何任务，那么它只会在构建任务期间生效，这可能会起作用，但不会显示在项目文件中

非常感谢您的帮助。

在进一步了解了这项技术的工作原理后，我提出了以下建议。希望这对其他人有帮助。欢迎提出建议
